“Notification stream selection update” : Gilles managed to run the test manually, after making some adjustments, in some specific conditions. “Fix Hybrid functional test race conditions” change allows solving these issues and running the tests in a more stable way.
“Fix GNPy functional test” change made by Guillaume allows to fix the failing of some functional tests associated with GNPy
“Improve container support in tox.ini” : promotes podman rather than docker as the solution for container, because Docker ……
Christophe made a review on Phosphorus migration. Everything seemed to be OK, but since this morning he has observed some issues with Phosphorus distribution (associated with NETCONF and Karaf). Nobody on the bridge had to work with Phosphorus so that we don’t know if these issues affect others or if it is limited to Christophe’s environment.
Christophe also observed another issue with the management of the OLM timer which is now directly injected in the Blueprint. After changing the timer several time, the modifications are not considered. Guillaume mentions that he needs to restart the bundle, since blueprint modification are not take into account if this is not done.
Peter is experiencing some issues in pushing his changes, so that he will need more time to do so.
We had an infra failure on Jenkins which generated a global failure, but this is solved.
Si SR2 has been released.
Guillaume has merged all the relation chain related to the parallelization of tox Test. In Jenkins, now, all tests are parallelized. A documentation is included (Change 97194). Locally, by default, tests are not parallelized.
“Refactor NMI notifications and ServiceHandlerImpls” & “Update NBINotifications” doc can be merged.
“Notification support for 7.1 devices” adds notification and tca listeners. This change has been there for a while and can be merged
“Notification Stream selection” has been updated, but Shweta needs some help. Modifying simulator’s xml configurations, changing Netconf stream from OpenROADM to Netconf does not solve the issue. Gilles will investigate.
“Power control support for 87.5 GHz spectrum”: Guillaume created a Jira ticket. Shweta will add some input to the renderer input container (nmc/mc)
“Use notification switching-pool in portmapping update” can be abandoned since we do not experience anymore the locking issue.
“Patch org-openroadm device 7.1” can also be abandoned since the serialization issue has been corrected in Phosphorus and Si SR2.
Guillaume made a change to fix unused dependencies warning now that we made a bump to phosphorus.
We are still waiting for LFN staff to release Si SR2. Dependencies have been changed. We will need to restage.
_Update karaf cache nc-notifications YANG schema : we may be able to use an updated version of the yang models even if they are in draft mode.
_Notification support for 7.1 devices : some comments have been made and need to be checked.
_Refactor NBI notifications and ServiceHandlerImpl : Thierry has started addressing the comments and recommendations provided by Guillaume and Christophe. The terminology used shall be in line with the documentation (and reversely).
_Peter is still working on his changes : sending NorthBound notifications as the connectivity context is changing
_Guillaume has started writing the documentation associated with the test parallelization.
_OLM management : New comment from Jonas regarding the fact that we use different channel width for 200DPQPSK, 300G QAM8, and 400G QAM16. Jonas is right, as all this rates use the same Baud rate and have the same roll off factor (max 0.20), we should calculate the same width = 63.1*1.2 = 75.72 GHz.
Si SR2 is not ready yet for managed project. We can expect it to be released soon. Could be next week.
No news for Phosphorus (SR0 planned mid-September)
Power control support for 87.5 Ghz Spectrum width : we need to clarify the constant we use (and probably adjust their names to make it more comprehensible) when we compare them with input.getwidth to make some decision and calculate the power for Flexgrid operation.
Fix OLM timer for ROADM crossconnect power setup can be merged
Guillaume has started refactoring the code of the OLM because it was raising a lot of Spotbugs issues and warnings (Refactor OLM PowerMgmtImpl class)
Thierry refactored NBI notifications and serviceHandlerImpl to address some comments and correct some issues. He has also updated the docs on NBINotifications
Notification Stream selection update : Shweta updated NetConfTopologyListener to read notification steams (OpenROADM or Netconf) supported by device and adjust the subscription accordingly.
Guillaume will be on vacation during 3 weeks. Christophe and Gilles will take their vacation in August.
Next week meeting is cancelled.
Phosphorus kernel project are almost ready, so that we could bump the dependencies. The code freeze which was planned beginning of August will be slightly delayed.
Si SR2 will also come at the beginning of August but shall be delayed.
Guillaume has merged a few changes :
Remove usless Netconf dependencies from features
Remove odl-netconf-connector-all dep from feats
Change tapi topology to use correct states
Christophe pushed 2 changes:
_Modify spectrum assignment in PCE : refactoring of the way to manage the spectrum assignment using a specific yang models rather than specific Java classes
_Update path description with OpucnTribSlots (WIP) : We still have some issues to solve. Christophe tried to align the path description with what is needed by the renderer. A leaflist is used for the min and max tribslot. Bala agrees on the fact that this shall be split into 2 leaves rather than using a leaflsit. The modification will be made tomorrow morning.
Al SR4 has been officially released. We don’t have any news from Phosphorus middle point timestamp.
Peter has pushed a change “Change Tapi topology to use correct states” to use correct operational and administrative state for ROADM to ROADM links, as well as Xponder to ROADM links. This code allows retrieving states from the mapping updates. Functions were added to get the correct state and insert it to the links. Some other functions are provided to convert OR states to T-API states.
Guillaume has started working on the test parallelization. This includes several changes (“Refactor tox.ini to prepare parallelized jobs”, “outsource PEC test scripts into a separate folder”, “Refactor tests launching procedure”, “Allow lighty build to listen to alternative ports”, “set different controller ports in tox test suites”, “Allow tox func tests suites to run in parallel”)
Peter Heringer has joined transportPCE dev team. He’s a student working with Nokia and will focus on T-API features.
AL SR4 : The branch is still locked. Christophe prepared a relation chain but we can’t push it.
OFC demonstration ran well, with a good level of attendance.
Developer forum : Gilles had the chance to have some exchanges with Robert about the tox job issues we are experiencing.
Guillaume proposed some changes to automate trailing blanks handling and merged some changes associated with linters
Christophe commented on the fact that very long chains lead to complex issues as many contributors are involved, especially when some of the new changes proposed are not correctly rebased on latest ones. We should try to avoid this as far as possible.
Some modifications were pushed on “update PCE for OTUC4 ODU C4 and 100GE Mxpdr”. The associated chain is fine
Patch org-openroadm-device 7.1 yang model allows solving temporarily an issue with the MD-SAL, when leafref are used in grouping. In the leaf-list port-list, leafref type has been changed from leafref to string, so that the serialization can be performed. This is a workaround. Gilles raised a bug in JIRA, MDSAL-668 so that the initial issue can be solved.
The change 7.1 Renderer must be put on top of this change.
“Reduce the number of service notifications sent” simplifies the way we handle the MDONS use case.
“Add service listener to notify Kafka “ : this change allows sending a notification to a Kafka broker when a service is down. The listener shall be moved from the network model to the service handler, since it does not have any connection with the topology.
Javier mentioned that some code will be released soon for the notification service. He is also working on the functional tests (almost done for the T-API module)
OpenROADM version fix : after some discussion it was decided to keep it where it is in the relation chain. Moving it to the bottom would require a lot of work and does not bring value.
Next week will be the developer forum happening at the same time as OFC.
Si SR1 shall be approved today. We shall be ready by next Thursday.
Next week meeting will be canceled so that everybody can assist/participate to OFC and the LFN developer forum.
Notification support for 7.1 device will allow to capture alarms for 7.1 devices. The change pushed on Master includes changes from Gilles.
Shweta pushed another change for switching-pool mapping update from notifications sent by equipment which solves a locking issue with the equipment that we had in previous version of the code.
Guillaume proposes to merge the changes as well as the one on Power control for 87.5 Ghz channels.
05/27/21 is rescheduled at 2pm Paris Time to avoid overlap with OpenROADM meetings
Silicon SR1 is in good shape.
Developer forum from the 7 to the 10Th of June is open to registration (free registration). Most sessions on ODL are planned on Tuesday with also some on ONAP. Unfortunately it is at the same time as OFC.
Guillaume rebased OTN topology on top of the fix he provided.
The dependencies for Si SR1 have been bump. We should now use these ones (odl parent 8.1.2, Netconf 1.13.2, mdsal 7.07…).
Guillaume has pushed a change related to this (Bump dependencies to newer Silicon dev versions).
This change and the change “Fix new checkstyle issues found by odlparent 8.1.2“ shall be cherry-picked and merged on top of the relation chain for Si SR1 .
The change of Bala made on stable Si will also need to be rebased after this has been done.
For Si SR1 we will have a fix for OTN topology and all what is above this patches in the relation chain.
Gilles pushed a change to update the configuration file for Honey node, providing some adds for 400G transponders and muxponders. This includes profiles. The file has been reorganized
Si SR1 branch is locked. Al SR4 should be coming by 2 or 3 weeks.
Gilles experience some issues but shall be able to prepare tpce staging for Si.
Committers election : Bala and Christophe have been proposed as committers. They got 100% accepts from expressed votes.The election must be now approved by the TSC.
Fix the misplacement of service notifications : Thierry made a change related to service notifications to avoid that notifications for service creation are sent before the service state is updated in the MD-SAL .
Some notifications were added in case the implementation of the service fails.
Guillaume proposed a few commits to fix some remaining build warnings and optimize gates logs and behavior:
Renderer interface delete for B100G TPDR change is needed for OFC demonstration.
Shweta pushed some changes to solve a number of issues with the PCE. One fix the issue about the fact that PCE doesn’t find SRG for unidirectional configurations. The other solves the fact that PCE picks the wrong a and z end termination points (first available tp even if not connected)
Bala is currently working on the Renderer for 7.1 devices, but did not succeed in solving the issue where the Renderer fails finding list of supporting interfaces. He may need help to understand this behavior observed with HoneyNode.
meeting canceled for Holiday
05/20/21 is rescheduled at 2pm Paris Time to avoid overlap with OpenROADM meetings
Silicon SR1 code freeze next monday for Managed projects.
Committers election proposal: 2 candidates Christophe and Bala => Action: Guillaume to prepare a proper poll to get others committers feedback
Next Thursday is Holiday and there will be no meeting.
Thierry proposed a fix for some issues with notifications: ongoing optimizations.
Javier's contributions on TAPI have been merged. They cannot be reviewed quickly by Gilles and Christophe.
The fact that there is no regression on current features is ensured. Javier will create JIRA tickets to refactor the code and imporve functiuonal tests.
Shweta is backporting to master her contribution on OTN and notifications for 7.1 devices but there are merge conflicts to solve before.
Bala presented his latests development on 7.1 portmapping functional tests and muxponders.
Gilles started also working on muxponder locally. They need to sync.
Si SR1 will be released the 12th of May, Al SR3 on the 6th of June
Guillaume wants to proceed to committer elections. Bala is OK to apply.
Guillaume is fine with the relation chain of the changes provided by Javier. Only “Initial OR-TAPI mapping” still has one point to be checked (NPE) prior to be merged
“New functional test for device change notification” is ready to be merged.
The last changes pushed by Bala fail when running the functional tests. It seems that the gate fails downloading the simulator.
Changing 7.1 to 7.10 in Functional tests: as we cannot consider modifying the enum in OpenROADM models from 7.1 to 7.1.0 (some equipment already developed according to 7.1 models) to align with other release naming convention, we decided to abandon that change that would bring confusion since OR must be considered as the reference.
Notification support for 7.1 device : Shweta will address the current comments made on the change.
OTN topology creation fix : Functional test were failing but they now pass.
Followed a discussion on the API between the Renderer and the SH and the adaptations that need to be performed to cope with the OFC 2021 demonstration.
Guillaume will ask next week for volunteers to the committer roles, as he wants to extend the number of comitter.
Add NBI notification feature documentation : the documentation has been completed.
Depending on the order the test were scheduled and if we were using lighty, some test returned either 201 or 200 code. Guillaume has provided a change to solve this.
Lighty is now supported on the SI branch
Bump deps to new Si dev version, may solve some issues uncounterd by AT&T. AT&T did not have the time to test it.
Shweta provided a change that solve some issues associated with Netconf operations translation (put->replace) on some vendor’s devices through “Update device transaction operations” change. Provided change allows solving this issue for power setting (OLM), connection setting and interface creation (Renderer) on all the devices AT&T currently has in their labs
A bug in OLM ServicePower Turndown (TRNSPRTPCE439) has been raised by Gilles, but Shweta explained that the issue raised in fact corresponds to standard operation.
In “Notification support for 7.1 devices” a listener is created for notification that allows to update the mapping when a switching pool has been created on a device. This change was developed on stable Si, but the code has changed since Gilles refactored this part of the code on master branch. Gilles propose to backport part of the code he has refactored (2 changes) to Silicon, and Shweta proposed to rebase her code on this. After that we will cherry-pick the change of Shweta on master branch.
Javier has been handling the comments provided through the different reviews on his code.
“Port mapping functional test for 7.1 device” change pushed by Bala is changing version naming in the different classes (7.1 -> 7.1.0). It is also modified in the xml config file, which leads to an issue in HoneyNode because the enum is not supported in the OpenROADM models. Port capabilities were also adjusted for network port changing if-cap type from if OTUCn-ODUCn to if-otsigroup. Guillaume proposes to split the change into 2, one focusing on 7.1.0 adjustments and the other handling all other adjustments.
Silicon is officially published and is available on the official download page.
Guillaume has merged several changes : “Increase sims startup timeout in functional tests”, “Improve docs/conf.py” and some Gilles contribution on changes in portmapping : “Handle notification reception on port state change” as well as “Refactor (un)registration of device listeners” and “Update portmapping on port state notification”
Guillaume pushed a change that modifies the script to install Honeynode, to improve the Gate behavior.
Thierry has provided the doc section that concerns nbi-notification module in developer and user guides
Silicon release is officially published.
Netconf is now MRI, meaning the project won’t use anymore snapshot which will make our life easier to manage dependency.
Guillaume mentions we could in this context, propose to be handled as a managed project for Phosphorus.
Anyway, this does not change the situation about our lack of committers and the way we are staffed. Being handled as a managed project brings a lot of constraints.
The developer forum is planned around the 10th of June and it will be a virtual event.
The contribution of Emmanuelle to the documentation on DMaaP client feature has been merged. NBI notification documentation will be provided during next week
Javier has been working on the changes associated with T-API. He has been running locally the test to check the code was not introducing regressions. This week, he has been focusing on the last changes of the 7 that were pushed.
“Initial OR T-API mapping Services” : Retrieves the services in the data store and maps them into T-API connectivity service (OC and OTU4-> Photonic, ODU->ODU, Ethernet -> DSR connectivity services)
“TAPI Netconf Topology Listener” : populates the T-API topology when there is a change in the mapping for the nodes
“Network Util”s : duplication of the tpce network utils yang models to create the elements in the T-API topology
“TAPI Topology service rpc Impl” : implementation of the NBI rpc associated with T-API (Javier is still working on it)
Guillaume provided some indications on the way to handle license models.
Then followed a discussion on B100G Muxponder and switchponders behavior.
Silicon has been released for managed project. Guillaume has created the branch and has released the artifacts for transportPCE.
Mg is officially end of life.
Gilles, would like us to set a rule to rebase the code before we merge it, to simplify things and reduce the list of commits.
Features introduced in Si have not been documented (nbiNotifications, DMaaP-client). A corresponding User story has been created
Renderer for 7.1 devices and Bump project version to 4/.0.0 snapshot have been merged.
Javier has pushed 7 changes for which tests are working locally. The three following changes are ready for review. Others are still work in progress.
_Creation of the T-API context on feature install
_Initial OR-T-API mapping : maps the OR to T-API topology on feature install. There are now 3 topologies, but only one is stored in the MD-SAL. This is the one where ROADM are not abstracted.
_Initial OR-T-API services : any service is mapped into the corresponding connectivity service in T-API (maintained in the MDSAL).
Javier will develop the Unitary tests if we are OK with these 3 changes.
Bala and Shweta made some tests and have end to end service rendering at 400GE. They demonstrate interoperability of both transponders and ROADMs supporting Flexgrid.
Some patches and further testing with the new Si release to come.
Silicon : The marketing message is in preparation. Managed project are still not all ready.
The Silicon marketing message for transportPCE has been reviewed and adjusted during the meeting.
The release note for Al SR3 has been released
OLM and Renderer module to support of 7.1 devices have been merged on both the master and the Al branch.
Javier had a call with Gilles to clarify the implementation of T-API context and topology mapping. A new change will be pushed shortly, so that the multilayer T-API topology is created and does not interacts with the code dedicated to the on the fly generation of abstracted T-API topology.
A set of changes has been pushed by Gilles and Christophe focusing on updating states in both the PortMapping and the topology, as well as for the services:
_Update portmapping on state notifications : This change allows the update the portMapping, using a new method updateMapping from notifications received from equipment
_Handle notification reception on port state change : the code developed by Javier has been refactored in order to handle device 2.2.1 and 7.1 in addition to device 1.2.1
_Set topology tp states from device port states : set tp states in openroadm-topology and otn-topology according to states of device ports in port-mapping.
_Update portmapping yang models : changes the structure of the portmapping using groupings so that java interfaces are generated to ease the access of each port independently
_Update node-tp and link states on topologies : when portmapping is updated, a listener of the mapping, created in the network module, allows to update the topology accordingly
_Refactor network topologies listener of SH : when a tp is supporting a service, a notification is sent to the SH if the operational states of the tp changes and affects the services. This change is derived from the code provided by Javier, with some simplifications focusing on tp state changes.
_Add new UT for deviceListener221 : this change is still tagged as WIP since some issues need to be solved.
Gilles made at the end of the meeting a presentation on Jenkins tox job issues encountered recently. These issues are related with the tox job duration (when it exceeds 2 hours) and build timeout constant currently defined. This leads to -1 vote on some of the changes. Something needs to be done. Splitting the tests across several tox jobs could be a solution.
_We have 2 new TSC members one from Pantheon and another from Verizon.
_Silicon code freeze is now effective and the branch is locked. We have not created it yet. We shall be careful when creating it because of the freeze.
_TransportPCE has been integrated in Al SR3 which has been released even if no communication made on it
_OFC event will be virtual (June 6 to 10), so that the demo will be handled in UTD.
All the relation chain of DMaap client and NBI notification has been merged on the master branch
Guillaume has merged the update of Portmapping for 400G.
Adapt PCE to compute 400G path has a merge conflict. Guillaume would like to Christophe to take care of remaining issues
Updated OLM Module : Guillaume is fine with the change but is waiting for some additional review.
Device Renderer to support transponder for B100G : Bala has addressed all the comments and will start writing the functional tests. Guillaume is also waiting for some additional review of it.
Bug in portmapping : solves some ordering issue sin the port list of the portmapping (v221). Guillaume asks to address the same issue in the portmapping(v7.1) in the same change.
Functional test for 400G : Christophe provided a test suite to verify path computation performed by PCE for 400GE. Shweta is about to complete her review of it.
Set topology topo states from what is in the portmapping: states in the portmapping are currently corresponding to the states that come from devices as they are mounted. Some changes to come will update the states in the portmapping from notifications received from devices.
Javier is currently testing his changes on T-API. No issues with the T-API topology saving in the operational topology data store.
He experiences some issues for the tests associated with some other changes (Initial OR-TAPI mapping, and T-API context saving), due to the way the feature is initiated.
We are in a self-nomination period for LFN Governing board committers.
AL SR3 is still pending. Will need to run the CSIT again.
Gilles provided an Upgrade for Honeynode. At that time it is limited to 2.2.1 device. It is a complete refactoring of Honeynode code to generate some notifications on port status changes. At that time Honeynode only send notifications when the status of a port changes (avoiding notification storms). A version for 1.2.1 devices and 7.1 devices will be available in a short time.
Guillaume added a profile in Tox to check any shell script s that may content bashisms.
He has cherry-picked Shweta’s works on OLM on master branch.
Gilles pushed 2 changes. The first is an update of the portMapping models in order to includes operational and administrative state of the ports. The second updates the PortMapping from value red in the devices. Next step will be to update portMapping from notification coming from devices.
Christophe has pushed on functional test suite to test the PCE operation at 400 G.
AL SR3 is not yet released but it shall be approved tomorrow, which means we will need to release next week.
Si ready for code freeze.
Gilles contribution on 400G has been merged. Sample device has been put on top of it.
Fix topology link and service update : Javier provided a fix to include in the ttpid the node id so that we can garanty the unicity of it. Guillaume mentioned that it would also make sense to have this change backported on Al.
When correcting the T-API context, Javier experienced a bug which has also been identified by other members of the community (https://lists.opendaylight.org/g/kernel-dev/topic/81062242?p=,,,20,0,0,0::recentpostdate,,,20,2,0,0&allview=1)
OLM Module : Shweta addressed all comments provided by Guillaume.
Both the OLM module and Renderer for 7.1 devices could be put on Al to simplify OFC demo preparation. However it will be pushed only in SR4 release.
NBI notifications and DMaap associated changes have been rebased by Emmanuelle. They shall be ready to merge.
AT&T presented at the end of the meeting some slides on the expected behavior of 400G switch and Mux-ponders, focusing on connection-map and otn switching pools.
Netconf is now an MRI (Managed Release Integrated) project and does not use anymore snapshots so that we need to adjust dependencies
Al SR3 is on track.
Self-nomination period for TSC additional seats.
Guillaume merged all changes on portMapping refactoring and cherry-picked them to stable-Aluminium.
Emmanuelle made an improvement to the test utils.
“HoneyNode for 7.1 devices” change has been cherry-picked to stable Aluminium to simplify the development of the test associated with the Renderer.
AT&T can use the HoneyNode for device 7.1 as well as the 7.1 400G Transponders configuration samples to develop their functional tests for the Renderer.
In “Update Netconf dependencies” (95324), we change the dependencies associated with Netconf, using the artifacts rather than the snapshots (see general information).
“Device Renderer to support transponders for B100G” : OpenRoadmInterfaces710 includes methods to create all interfaces needed for B100G (OTSI, OTSIg, OTUC4, ODUC4 and ODUFlex, and 400G EThernet…)
The code for OFC shall be ready by the end of April. Even if we are not willing to push the high rate renderer in Al SR3, we shall try to keep it on the Al stable branch.
OLM also needs to be cherry picked on Al.
Silicon shall be released in March.
The Si code freeze will be next Monday.
Al SR3 could come soon. They have solved the vulnerability issue they had with Al SR2.
Not only the Netconf dependencies may change, some others may also change. Guillaume will ask to the TSC.
Guillaume continued working on the optimization of the code for PortMapping. Several changes have been merged on both Si and Al : Add a portMapping method to retrieve Xpdr port 2, Improve portMapping LCP method to map degree, Fix+ align portMapping protections and log messages, Fix usage of deprecated methods in portMapping. Lists have been changed to Maps to be compliant with Si usages.
Gilles made several improvement to T-API : “Update topology input files for T-API topology UT” focuses on taking into account admin and operational states of openroadm-topology and otn-topology as well as Flexgrid data. “Align tapi topololgy states on OR topology ones” allows to set the state in the T-API topology from the state that are present in the OR topology (they were hardcoded in the intermediate phase)
Emmanuelle has been working on refactoring the GNPy code, also introducing the Jackson serializer/deserializer missing in Yang Tools.
Manage 400G in portmapping is a preliminary work needed to handle higher rates. A sample of 7.1 device configuration for transponder at 400G has been proposed by Gilles. He would like it to be double checked by AT&T who has the knowledge of equipment. AT&T highlights from what they saw in the labs, that for transponders @400G, most of the time the connection map comes at run-time, because the same devices can be used as transponders or switch-ponders (depending on the type of equipment, we could have either a connection map or a switching pool)
Gilles will populate the repo so that it allows the installation of HoneyNode for 7.1 device.
“Adapt PCE to compute a 400GE path” change allows upgrading path computation, considering port capabilities of transponder and is a preliminary work needed to handle higher rate
AT&T has started working on the renderer for higher rate. They may have an update, maybe not on next week but the week after.
Guillaume confirmed that it is probably better to work from Stable Al branch for OFC, since Si may suffer from instabilities.
Al SR2 might not be officially released (Issue with authentication in NETCONF/RESTCONF)
AT&T wanted to have a discussion on which version we should rely on to perform the demo. Bala propose to make the development on stable Aluminum and later cherrypick it to master. This will allow to rely on a stable branch.
For functional tests on Kafka we use docker compose to create the docker image from a Yaml file. The docker image is not available on Gerrit.
The YAML file is available on the change “add test for service notification” (94272).
Gilles has merged recently all changes pushed by Javier on Topology update.
He has proposed a change to bump our dependencies on Silicon.
He has merged a few changes regarding dependency injections to solve some issues with the T-API module.
Guillaume is working on some refactor on the portmapping.
NBI notification for Kafka is still under review. Emmanuelle has solved the issue regarding the NBI notification module
Fix variable name in topology allows fixing a bug we had. The input file used for unitary test in topology have been changed to take into account the admin and the operational state that are now handled
Gilles also made a change to adjust the state in the T-API topology to reflect the state that are in OpenROADM topology.
Emmanuelle worked on a Dmaap client, in the same spirit as the NBI notification module adjusted for operation with the ONAP Dmaap Bus. This will allow to handle the asynchronous process in MDONS.
Javier has pushed some code as Work in Progress
_”T-API context creation on feature install” (when the T-API module is installed). He is still working on solving the issues he encountered
_”Initial OR-TAPI mapping Topology” focuses on mapping OR topology to TAPI topology and store it in in T-API context
_”Initial OR-TAPI mapping: OpenROADM Services” : OR services are mapped in the T-API context
_”TAPI Netconf Topology Listener” – provides a TAPI network model service equivalent to Network Model module –
_”TAPI network utils” allows the creation of links in tapi
Javier will make a presentation to summarize the content of his changes.
AT&T mentioned that the renderer for B100G might be ready mid of next week.
Al SR2 should be announced today.
DDF is starting next the 1st of February. ODL sessions will be on Thursday.
Javier divided the T-API module User story into several topics (Initial mapping, Netconf listener, Service Handler, implementation of T-API notification service). He is working on it locally, and will push the code when it makes sense
OLM Module : Shweta uploaded a new patchset. It has been tested in the labs. This changes addresses PM retrieval for 7.1.0 models, power management for 7.1.0, and power management code to support hybrid network . She also handled the correction of a bug in provisioning MC. This should no longer be considered as Work In Progress.
We are currently experiencing an issue (with yang tools / NETCONF?) when we introduce in the filter the PM resource type extension with HoneyNode.
Gilles has raised a bug on TPCE-JIRA: when we try to install the new feature for notification, the bundle cannot be started. This might be an issue with the MDSAL. The issue description will be sent on the odl mailing list.
Gilles also pushed several changes :
_Service datastore instantiation in SH : checks correct instantiation of Service datastore to avoid null pointer exception if this is not the case when the sate of a port is updated.
_Fix the SIP UUID generation in Tapi Topology : change the way UUID are generated so that they are created in a deterministic way for the service interface point.
_Set mandatory UUID in TAPI connectivity module : In the t-api connectivity module , sets a mandatory UUID to avoid any compilation issue.
_Reorganization of dependency injection in Service Handler : solve the Service Handler instance duplication issue when installing T-API feature. It also removes manuel instantiations from ServicehandlerProvider to let blueprint manage object instantiation as a singleton, adapts constructors of service handler UT accordingly and reorganises dependency injection in lighty to be aligned with blueprint files
Guillaume started to add some intermediate methods in the Port Mapping (This is still WIP)
The meeting ended with a discussion on PortMapping : with 400G equipment when we have a Transponder without any circuit pack provisioned we do not have any connection map populated. This comes up (as well as the switching pool) only when the client and network are introduced in the transponder/muxponder. We should be able to refresh a port mapping on notifications coming from the insertion of a new circuit-pack in a transponder/ muxponder unit.
Al SR2 : No news from the LFN staff to publish the Artifact. Robert tried to address this and getting things moving forward.
Developer and testing Forum is from the 1st to the 4th of February. Guillaume will propose some topics about documentation.
Javier contributions have been merged this morning.
Flexgrid has also been merged on Master branch.
Resource deletion issue in OpenROADM topology : following the creation and the deletion of a service, the resources were not correctly released.
The bug has been fixed by Gilles.
Shweta is currently working on functional tests on OLM. She is experiencing some issues while trying to access specific PMs using filters.
Current master branch now based on Si works back again.
Current master branch now based on Si is broken.
We are experiencing a compilation issue with newest YangTools.

Last change is concerning the functional tests associated with this new functionality (Kafka notification publishing)
Magnesium SR3 publishing is imminent. CSIT issues have been fixed
Al SR2 : the release manager proposed to postpone it to January the 4Th. As self-managed project, the deadline for us will be the 11th of January.
Bump to Silicon : before merging all changes for Flexgrid and the changes of Javier, Gilles feels it would be good to merge “Bump to Silicon” Change.
Guillaume rebased the change on master, and Gilles then will merge it, once the gate will pass.
Mg SR3 release should come soon..
Guillaume worked on the second step to align the different versions of the PortMapping.
Mg SR3 branch is still not locked (infra issues more or less fixed but still CSIT jobs failing).
Update on HoneyNode simulator: with last version of jdk 11, regex does not work anymore to retrieve the version of the equipment. This has been corrected in this change.
Mg SR3 branch is still not locked (fixing infra issues).
Honeycomb modifications on 1.2.1 have been pushed to Gitlab.
Changes associated with Netconf notifications handling have been pushed on Gerrit (Step1 to 8).
A thread is created for each notification to avoid bug identified as TRNSPRTPCE-249. Step1 to 6 were introduced during last meeting.
Step7: When a service notification is received by the Service Handler, this last compares the elements of the topology and their states with the elements included in the different path-descriptions of service-path-list.
The state of the services affected by these state changes are refreshed by the SH.
Step8 : Honeynode 1.2.1 simulator has been modified to include the implementation of Circuit Packs notifications in DeviceNotificationProducer and the implementation of CP update datastore in DeviceChange listener.
We are part of Al SR1, though it seems the marketing annoucement are not more brodcasted on the mailing-lists.
Guillaume added pyang tox profile to check/format api models and the documentation spelling.
Gilles proceed to release of Al SR1 last week.
Mg SR3 : Code freeze for Managed project will start on the 16th of November.
Emmanuelle has aligned the topology on 7.1 openROADM models (Common, Device, Network models). She split the changes to ease review, meaning a lot of them do not pass the gate.
Managed project are ready for Al SR1 since today. Gilles is going to prepare the staging of the release.
The latest work done on T-API will not be integrated in Al SR1 since it is still in review.
The TSC election process has been postponed to the end of November (but self-nominations coming soon).
Lighty support in Al : Lighty now works with Al (add annotation dependency, increased memory allocated to make it run, PathComputation service Impl was using BindingDOM codec service from karaf which has been changed to AdaptorContext serializer)
Now that lighty is activated for the test, TPCEUtils also needs to be updated if we change models.
Using Lighty on Al, we will rely on a stable version. But for Silicon, Lighty needs to be uploaded from maven central, and it is not currently available. This is the reason of the change “Lighty support Silicon migration”
Portmapping for 7.1.0 models : Bala changed the portmapping to enable 7.1 models. Supported interface capability implementation has changed. Interface capabilities are now more port childs but are now handled as an augmentation and mc-capbilities are now handle through profiles.
Emmanuelle mentions that she will wait for the portmapping to be merged so that she can rebase her Topology change (common models need to be changed for both) .
7.1 Honeynode simulators can be downloaded from
Bump to silicon : Guillaume split the change done by Emmanuelle since he wanted to reuse some of the code changes in AL
T-API : Gilles made a change to strengthen independence between UT in OLM (not strictly related to T-API). A second change allows sharing a common Datastore context for all unitary test in T-API (Static class). The 3 following changes are dedicated to the consolidation of T-API topology. Only ports and node that are attached to the ROADM are considered. Second step allows to build a multilayer topology that includes both transponders and OTN devices. Step3 allows building the same abstraction as we were building in the initial development (only transponders and WDM layer). Last change includes the tests associated with T-API.
Aluminium SR1 deadline is tomorrow for managed project.The branch has been locked this week.
It will be unlocked when managed project will be ready which will allow us to migrate.
There were a couple of evolutions on dependencies, which have been considered but can’t be merged in the current state.
Bump to Silicon :
Emmanuelle updated the Pom to Si as well Junit tests and code to be in line with Si following the introduction of the Maven Enforcer Pluggin.
The change also takes into account the latest modification made by Robert to solve MDSAL-600 bug (Problem when using two enum with the same name in the same module).
There will be a TSC election in the coming weeks.
When upgrading it to 7.1, two approaches can be followed.
First Approach : Create 2 separate yang files for the attributes that have changed in new versions.
Second approach: we would use the most recent model (7.1.0 ) for all older model as well.
This implies to make some deeper changes. We have a global agreement on the fact that the 2nd approach looks more appropriate.
The migration of network models to 7.1 has been initiated on Orange side by Emmanuelle.
Robert has recommended to use BOM in the POMs. Guillaume initiated some work to use BOM in tpce features.
Guillaume also removed some useless findbugs jsr305 dependencies in the common and in the Tapi modules poms.
Add OpenROADM 7.1.0 device and common modules : there is still a few comments to be addressed befor the change get merged.
SH handler optimizations and technical debt is ongoing, but Guillaume is expecting feedback on how to manage the pending status.
Lighty.io : Binding DOM codec service is needed by GNPY but not supported by lighty.io. This means some rework is needed on the GNPY API.
Bump to Silicon SR0 version is working. The changes is expected by committer(s) to be split so that other branches benefits from the improvement done
(and also to ease their maintenance).
Javier expect to push by tomorrow some part of his work.
Robert Varga presented his notes on ODL during the LFN events.
There will be some changes in the way notifications are handled in next releases (implementation of RFC8040)
Bala posted a new change on Gerrit that corrects warnings coming from Pyang analysis on yang files.
Bala would like to organize a meeting about portmapping 7.1 since he wants to discuss about some issues he encountered.
Because of the change in the way port/mc-capabilities are handled in OR 7.1 release (common model),
the PortMapping needs to be deeply modified to fit with the new models. From swagger UI the version of PortMapping does not appear anymore in api-doc.
Emmanuelle pushed some changes on stable/aluminium on technical debt.
She is waiting for netconf silicon migration to migrate master branch to silicon for TPCE
Gilles and Christophe worked this week on the consolidation of T-API topology export :
the topology will include the NEPS of the photonic layer that corresponds to Xponder ports that are connected to the ROADM infrastructure through fibers.
ther port (that cannot be commissioned) will not appear in this abstracted topology.
Tpce is officially in Aluminum, even if the official announcement still has not been sent to the mailing-lists.
Next week will be LFN networking technical event (old DDF) handled from the 14th to the 15th of October. It is a free event but a registration is needed.
7.1 Device model :
In the ModelMappingUtil it seems we have some duplications of the settings of serviceA/Zend where OUT, ODU and clli are affected 2 times. A change is dedicated to this.
CleanUp API yang changes (part1/2) look fine.
Augment 7.1 device common model : we have a licence issue with the OpenConfig Models (missing license). As we cannot convert the Apache L2 license into BSD license, the separate license file needs to be added.
Fix bug on transitional link solves a UUID creation issue : 2 devices could have the same UUID for the transitional link leading to the creation of only one link. The creation of UUID has been modified to address this issue.
Add OTN links in TAPI topology : OTU4 and ODU4 links are now provided in the OTN topology. Associated Junit tests were added.
ONES virtual event is ending. Video can be seen offline for people who registered.
CPQD (A Brasilian institute which promotes dirsruptive technology) seems interested and asked some questions on tranportPCE
LF Networking (equivalent of DDF for ODL) virtual event is following (13-15 of October) : they are still asking for late contributions.
Aluminum official announcement was still not done, as they are waiting for Release Note updates from some projects
Device Model 7.1 : now compiling. Bala is expecting a review of it. The change includes refactoring of transportPCE API
Func test for Flexgrid : Gilles made a review on it and the test suite has been merged.
Documentation : Guillaume added some elements on the T-API feature to the user guide. The release notes have been updated
Python functional test rationalization has been merged
Junit test : Move common DataStore has been merged last week. Guillaume is currently focusing on 92439 “Migrate AI and reactivate some Junit tests”.
Lighty.io 13 was released on the 18th of September. Guillaume started to look at it. GNPY dependencies were forgotten. PathComputationImpl needs BindingDomCodecServices which leads to the same issue as for the Junit tests (92349).
A couple of change waiting for review, from which “do not explicit serial Version UUID anymore”
Shweta has identified a number of bugs on the OTN code. Corresponding JIRA ticket have been created.
We will be part of the Aluminum distribution which shall be released today.
Release plans for next Silicon release have been asked to core projects.
In the case of TransportPCE it does not bring that much value since it would concerns mainly functional features, but no API modifications
Forgotten Mg Branch documentation update has been cherry-picked to master and stable/aluminium.
Aluminum Developer guide documentation has been merged, as well as the user guide which was modified regarding the installation of T-API feature
Do not explicit Serial Version UUID is ready for reviewal.
Guillaume has been working on rationalizing the Inventory
_Junit Tests : Guillaume splitted the change on Junit test
_Remove dead code from Junit test has been merged
_Fix test-common dependency scope in some pom files has been merged
_Fix a bug in PceUtils Junit can be merged. The proposed correction was made because initial Junit test was failing
_Migrate to Al and reactivate some Junit tests & Move common DatastoreContext and co-test-common lead to some issues
Guillaume fixed pylint configuration, modifying default regex rules and solving some false positive issues.
Use dict instead of elif in functional tests : some dictionaries have been introduced to simplify the code in some test suites
Managed project are almost ready for Aluminium . A message was send so that the PTL provide their inputs for the marketing message.
We should be ready by next week (25th of September) The documentation may need to be reworked to include Flexgrid
All Aluminium bump have been merged on top of Flexgrid.
Migrate Junit test is still not merged because……..
FlexGrid test suite : Gilles made some reviews and comments on the test suite, asking to include the renderer in the interface creation process (MC and NMC). Bala pushed some new tests to address these comment. The test passed the gate.
Rationalization of the inventory code : consolidating the Al migration, Guillaume made some changes on the Inventory.
Functional test rationalization was reviewed by Gilles. However, we will merge this patch after the migration to Al just to make sure there are no side effects.
Update device model to 7.1.0 : ODU 4 and OTU4 identity are imported from otn-common types. Some wrong revision are imported leading to mismatch. Still not clear why we observe this behaviour. We do not plan to include this in Al release.
Al SR0 is planned for next week on the 17th (Managed project). We have one week left to finish the migration.
ONS is on last week of September and will be a virtual event with limited fees.
Update of device model to 7.1. In the common type, there were some identity that have been added and some have been deprecated. In java classes generated by MD-SAL the dash is suppressed from deprecated identities making this redundant with the new one which leads to issues. This is probably associated with a bug in YangTools. Deprecated identities have been removed. Suggest to raise the issue in OpenROADM to remove deprecated identities from R8.0.
Flexgrid : Potmapping, flexgrid rendering and test suite changes are ready for a functional review.
Guillaume changed the docker image for ROADM D (that includes mc-capabilities)
Functional test cleanup is not completely ready, but a couple of change are ready for review. Pylint configuration have been modified. Simplification of the tests using dictionary with checks to be done instead of elif.
Aluminum migration :
In GNPYBindingDOMCodec services is used instead of direct implementation. GNPY yang models have been adapted to remove the key for the list of include/exclude constraint to solve a problem of ordering in the resulting Maps. The corresponding change is now ready for review.
The PCE has also been changed to solve a number of bugs associated with list and map handling.
Bala is asking for postman collection to help debugging the functional tests
TransportPCE will be part of the Na SR4 distribution
Flexgrid : the Mg SR2 dependencies were removed from Nexus, so that Guillaume upgraded the dependency to Mg SR3.
The code can now be rebased (as an intermediate step since at a later step it will need to be rebase on Al). Bala still has some issue passing the functional tests (all 1.2.1 port-mapping related test are failing. Also some of the Junit test are failing.)
Some of the input of Junit tests are hardcoded, so that if new mandatory parameters have been introduced, there must be fed to the Junit tests.
Migration to Aluminum ongoing work :
· GNPY feature to reactivate: the problem comes from the Yang Parser factory. The Yang Parser factory has to be reinjected.
· Migration of the functional tests that are now in failure following the API migration. see belo
· Binding context. Karaf tries to load the package mdsal.codec.impl but it is no more exported by mdsal (modification in poms).
· Guillaume is asking for some review on the PCE. He made some modifications to have it working but these modifications are not really on the same line that the initial proposal.
· Guillaume had to increase the Karaf Java dedicated memory size to have functional test passing.
Magnesium SR2 released. TPCE merge-release job passed tuesday. We should be part of Mg SR2
Gilles did most of the premilmary work to bump to Alumium but it is not yet completed.
This was a huge change, Onoging work to split it.
Aluminium does not buit with jdk 11.0.4. The version used must be at least 11.0.6
Among other things, the API change impacts yangtools generated lists.
The type used is now Map instead of List.
Some bugs found on real equipment with Mg SR2. JIRA tickets to come.
Flex grid stll on work, especially functests that needed an update on honeynode (now merged)
Magnesium SR2 : there are still some issues with some of the Managed project artifacts.
Some issues in developing the test suite for the flex-grid capability. This requires the device to advertise mc-capabilities for degree/SRG in the operational data. A new operational data file (oper-ROADMD.xml), where these capabilities were added has been created. However, mounting the device using the honeynode-simulator, only the operational data appear.
The kernel dependencies have been updated this week.
The gate is back and we don’t see anymore the karaf issue that were encountered last week.
We will need to check the documentation in case that dependencies are changed again
Once the managed project will freeze we shouldn’t see anymore the error stating that the Netconf artifacts are not available.
Otn-link update fix : addresses a bug associated with the update of the tp after a new link has been created.
Flexgrid portmapping change : AT&T proposed to introduce in the mapping list of the portmapping yang model a container mc-capabilities with slot-width and center-frequency.
The reason for this is that we could have hybrid node that support only Fix Grid on a degree and FlexGrid on others.
Bump project dependencies to Al : Gilles as started the migration towards Aluminium release.
The last release provides a lot of changes especially in the common modules (Serialization of object toward Json or xml, functions to parse yang models. So this migration will be a difficult exercice.
Missing modulation format for 2.2.1 Och interfaces needs to be reviewed.
For self-managed project Mg SR2, we have up the 20th of July to stage the project.
Branch lock is anticipated to the 13th of July which may lead to a branch lock that happens very early.
If we want to merge something, this needs to be prepared tomorrow, because of next bank holidays in France.
AT&T would like to check the code on equipment. If a bug is detected and a patch is proposed to solve it, this could be submitted to a super-committer.
In “Update docker command” change, Emmanuelle proposes a new way to start the GNPy docker.
Na SR4 distribution has been approved. No detailed schedule announced.
The team from Nokia has joined the meeting.
Kafka and MongoDB are probably not supported in ODL (dependencies not present in ODL). It will probably need to be put in a separate place.
This is the DDF / virtual event week .
TransportPCE was presented. Some questions have been raised about GNPY. A session was also handled by Robert Varga and Guillaume about LFN process.
Many improvements on Functional tests merged. Better process and strat-up sequence management.
Alignment of 1.2.1 and 2.2.1 tests: Guillaume has modified the functional test so that they all use the same approach. A dictionary is used to define all simulators to be launched and the port they will use.
ONES virtual event planned next week.
Orange proposed 1 session for TPCE, 1 for BGPCEP and one about LFN infra migrations and ODL scheules synchronization.
Some bug fixes on the OTN nodes
There won’t be any ONES EU event. It will be replaced by the virtual ONES NA event in September.
SH-Renderer-API: Bala will start looking to Olivier’s comments beginning next week. Guillaume proposes to rebase this change on the current master.
Artifacts for Na SR3 have been published.
NETCONF-666 bug has been corrected and merged on Mg. It may solve the issue we observed with NETCONF notifications generated by devices in case of multiple Netconf sessions.
We are officially part of Mg SR1. It will be announce today or tomorrow.
Deadline for managed project for Na SR3 is tomorrow. We are ready for integration in this release, but Netconf artifact is still missing, so that we cannot stage the release.
Wiki URL has again changed from wiki.lfn… to wiki.opendaylight.org, which brings a lot of issues. Guillaume sent a mail to highlight this.
Ongoing discussion on the virtual ONS summit.
Sprint planning is on next Tuesday. Please make sure all user stories of interest for you in the backlog!
ODL TSC is working for Mg SR1 releasing, but the branch is clearly not ready to stage the release.
The old Wiki has been migrated to the new Confluence Wiki. All the information is there. Module description and Requirements are at the same level. It will be updated later on.
Orange will close the sprint on Jira. After everybody has made some refinement on its user stories (acceptance criteria, detailed description….) we will start building the backlog of the next sprint so that we can set a new Sprint-planning meeting. Proposed date for next sprint planning is the 2nd of June. The period for next sprint will be from the 1st of June to the 25th of June.
No news about the release to come. It seems that the community is pretty late.
Shweta proposed to give help on reviewing the 2 changes pushed by Jonas.
First contribution is about lldp neighbours discovery, changing some loops behavior.
In the 2nd, PCE optical node validation, Jonas corrects the PCE behavior so that if PP ports on an end SRG are already used path, computation fails.
The presentation made in the TWS meeting was appreciated and a question/answer session will be organized next Monday.
Next LFN events : No news from next Developper forum, the ONS America has been postponed to September but it is not canceled
Mg SR1 : we can’t stage the project right now, because managed project are not ready. It shall be possible next Monday. Hopefully, we shall have one week then to stage transportPCE
A new version of checkstyle does not allow separation in the import. Stable Magnesium and Master are now pointing to Mg SR1.
Upgrade to Service Model 6.1 : propose to put it on hold and wait until the issue 678 of OpenROADM is solved (bug related on the introduction of mandatory leaves making the subrate-eth-sla container mandatory whereas it is associated to a when statement, which leads to incorrect behavior in ODL). Then rather than integrating R6.1.1 which shall solve the issue, we could directly jump to R7.1 which will also solve this but add nice features to handle MDONS use case (such as the possibility to handle several notifications urls to different ONAP subcomponents.
The mailing-lists have been migrated, this includes transportPCE dev list.
The presentation about transport PCE for the Tech work stream (public session) will be on the 27th.
It has been asked by the TSC, and shall be technical. A good starting point could be to reuse the presentation made top OpenROADM user Group.
The gate was broken two days ago, this means the project shall be rebuilt if no Maven cache repo is used.
Narayan has started working on the support of 2.2.1 Devices in the inventory. He has an issue with the database management.
“Upgrade OpenROADM service model to 6.1” : Susmitha has removed old 5.1 service Model.
She suggests to keep old models in common, because a lot of modules are still using them.
A release note and a marketing announcement have been prepared. All self-managed projects (including transportPCE) will be in the official distribution.
GUI source code has been published on Orange public Gitlab, the docs have not been published but exist in Microsoft Word docx format, they must be converted in MarkDown.
Several change have been made to reduce the technical debt and fix different spotbug issues (Separate changes for PCE, Common & Network and Renderer modules).
This changes also allows solving some of the SONAR issues.
There will be a vote today for Magnesium Release, but they are still experiencing issues with some of the projects.
Guillaume did not manage to stage the release because some dependencies are still missing.
“Update configuration files and tests” change is focusing on correcting the clfi and addresses of the nodes, and managing OMS attributes and other deprecated attributes that were moved to the common model.
Magnesium release is postponed. A bug in karaf prevent some of the modules to start correctly.
Trying to stage the release, it seems that some NETCONF dependencies are not available so that we can’t stage it.
Bala has been working on checkstyle issues for SAPI/DAPI code and will push it this afternoon.
We are working with Fossology to check the licenses associated with the GUI code. After we have checked licenses are compatible, the GUI code will be pushed on Gitlab.
Magnesium will probably be postponed but we are ready to integrate the release.
We have received some guidelines about the migration of the Wiki (Casey Cain).
The documentations have been reviewed to include OTN support, GNPY, and T-API support (for the export of the topology).
Some example have been provided to explain how to configure OTN devices using intermediate (East/west) APIs, waiting for a full end to end support (planned in later releases of Magnesium).
We manage to release tpce for Na SR2.
Magnesium code freeze should have been on Monday the 10th of February. Bus as BGPCEP project is not ready, Mg shall be stable only on next Monday.
Guillaume has bumped the dependency and also migrated tox to use controller with JDK 11 and sims with JDK 8(not merged at that time).
Currently the project is building with JDK 8 and 11 with Sodium. JDK 11 is mandatory for Mg.
AT&T has started working on service and network models 6.1 integration. There are some issues , probably coming from common models.
Bala has also started working on including SAPI and DAPI field on interface Builders (OTU4 creation) in the renderer but functional test fails (at the Topology level)
AT&T identified an issue with ODL parsing device responses to Netconf config edit. They need to investigate a bit further to understand whether the issue comes from ODL (NETCONF) or from the equipment.
The next DDF won’t be collocated with the ONS. It will be associated with the ONAP event in Seoul.
