Argon SR1 should be published soon since it has been approved by TSC. Argon SR2 is planned end of July. Potassium GA is planned end of September
Bala experienced compilation failure on the master branch which has been updated to Ar SR1 (SingleFeaturetest of odl-transportpce feature). Christophe tested it on his side but does not experience that issue...
Bala made a presentation on his implementation of the alien wavelength use case in transportPCE.
A maintenance operation is scheduled Friday the 5th of May on the Jenkins servers.
Cl-SR3: ODL distribution should have been released 2 weeks ago, but there was no TSC approval. It still has not been released.
Argon SR1 is under TSC approval today
Upcoming LFN testing and developing forum will be held in June. Submission deadline is on the 19th of May
We need to take care in the way we handle Jira Ticket and specifically the resolution version, because it affects the Release notes.
Status on changes merged since last meeting:
After a very quick review of the stories we put in the backlog, Sprint 32 was started!
Next upcoming LFN Developer & Testing Forum will be held virtually from June 6th to June 8th. The deadline for topic submissions is May 19th

Status on changes merged since last meeting:
Bala is working on the IPoWDM use case. Had a discussion on the flow to conform with during the creation of services. For temp-service, in the specific case of optical-tunnel, the service shall not be created on devices. If it works with simulators, real equipment (SRG/DEG of ROADMs) may have no way to set up connections and adjust power level through specific control loops as the transceiver are not activated (no input power on ROADMS). For this reason Olivier suggest that the process of service creation shall be interrupted but all information to setup the optical tunnel in a second step shall be store in the Database (At least for service, and its path). For what concerns the topology, we need to investigate...
ODL Argon distribution has been officially released. The TPCE release note still needs to be done. SR1 is planned for the 27th of April. It will include all OSGI refactoring and the correction to the developer guide.
Status on changes merged since last meeting:
Gilles will try to rework the nbi-notification to integrate the change provided by Nathan to add kafka messages, starting week 16.
Argon release is still ongoing. Netconf released a new version for Ar this week. Gilles took into account this change and released new Ar artifacts for both tpce and tpce/models. Apart from the release note we are ready.
S-SR4 using Java 11 is also about to be released. Gilles started the bump to latest upstream dependencies.
Status on changes merged since last meeting:
A discussion about IPoWDM use case, which Bala wants to handle, was engaged, around “Initial support IPoWDM use case for OpenROADM” Jira ticket (https://jira.opendaylight.org/browse/TRNSPRTPCE-739).
ODL Argon release: it seems there are some regressions in the LFN processes due to the migration to Python 3.10. On TransportPCE, just the release note still needs to be done.
Status on changes merged since last meeting:
After Gilles has merged his relation chain, he will take care of the Nathan change, refactoring the NBI notifications as soon as possible.
Since Argon, Java 17 is needed to compile TransportPCE
ODL Argon release: we should release ODL Ar today. Last week, Gilles released all artifacts related to transportPCE after having merged all pending changes. Will remain the documentation to handle. Olivier will write a paragraph on impairment aware path computation.
Next deadline is Cl SR-3 on the 8th of May
Sulfur shall also be End of Life today. However, ODL community proposed to release Sulfur SR-4 as a courtesy release. We are invited to provide the corresponding tpce artifacts.
OFC: Nokia presented a demo “Network Management as code”. Javier will share the paper. Nokia also shared in OFC some elements on T-API 2.4. There were almost more than 11000 attendees in OFC this year, which brings it to the level we had before the pandemics. Nathan made different demonstrations based on One Engine and TransportPCE. UTD observed some contention issues with tpce when PMs are also polled by One-Engine. The provisioning of a service then can fail. Nathan changed the code to poll the PM directly from the device rather than passing through tpce. The problems is associated with configuration locking while reading the configuration and potential associated time-out. Guillaume mentions that this could happen when device do not have any candidate Data Store. Gilles mentioned that his recent change on the refactoring of the RequestProcessor class may solve this kind of concurrency issue.
Status on changes merged since last meeting:
Argon will be released the 16th of March. We are almost ready on transportPCE side. We will just need to bump the upstream dependencies to their latest version. Sulfur will be at that time EOL.
Cl-SR3 is targeted on the 8th of May
Status on changes merged since last meeting:
UTD question (Nathan) about the issue with Karaf Logs: is it still the case with the latest versions of PCE?
The Karaf client, no longer working is an issue we had some time ago, and which is not solved with the current Karaf version. It is an upstream bug in the Apache Karaf project. Karaf server is however still usable. So Karaf client does not need to be launched to observe the logs. However for UTD who wants to extract some messages from the LOG, it could be an issue. Lighty was not deeply tested by UTD. UTD is asking whether they should move to Lighty to solve this issue. Gilles answers that to him the real way to solve the issue is to use the nbi-notification module. However Nathan mentions that a lot of information is needed by their application, which would imply to write a lot of code to complement current implementation. Gilles explained that each TransportPCE module communicates to other modules through the mdsal-notification mechanism. Looking at the logs, it is quite easy to figure out which are the notifications sent through this process, and if need be, complement them and filter them from the Karaf Logs...
Status on changes merged since last meeting:
Gilles created a new relation chain of changes in the scope of the migration to Argon:
Since a while, Bala has experienced some issues with the equipment in the labs, on their candidate datastore, deleting interfaces (this is even not using the renderer, but doing it directly on the device pointing to the right url). He will provide more details about it.
Gilles observed on his side that we regularly lose during the tests some Netconf sessions. Bala observed previously the same kind of issues which were solved setting the Time_To_leave parameters.
Status on changes merged since last meeting:
OpenROADM device model update: it seems more reasonable to update the device model directly to 12.1 rather than 10.1, since it should cover all required functionality (GCC option, Y cable, 800G modeling…)
Status on transportpce changes merged since last meeting:
Status on transportpce changes merged since last meeting:
An equipment manufacturer works on R10.1 of device models. Bala did not identified major changes from 7.1 to 10.1. But the support is required in PortMapping. Rendering part should not be that much affected. The migration to 10.1 shall be needed to test the product as it will be released in the Open Lab. Currently UTD has one of their equipment which is a Switchponder with 100G line port. But the new unit shall be a 400G transponder. Having an example of configuration file for TPCE sims would help a lot.
Gilles released last week transportpce artifacts for Cl-SR2. ODL distribution Cl-SR2 should be delivered very soon, on time
Tomorrow is the deadline for submitting topics to the LFN DDF (13th to 16th of February) which will be virtual. Registration is free of charge. https://wiki.lfnetworking.org/display/LN/2023-02+LFN+Developer+Event+Topics+February
Guillaume proposed a contribution about the migration of the tests towards RFC 8040.
For mentorship (trainees can be funded by LFN), the deadline is the 3rd of March : https://wiki.lfnetworking.org/display/LN/LFN+Mentorship+Program
Status on transportpce-models changes merged since last meeting:
Status on transportpce changes merged since last meeting:
Bala is using Inteligy IDE, but can’t see the import of the OpenROADM yang files. This is associated with the move of those to transportpce-models dedicated repository. They should appear in external-dependencies when selecting project files view in this IDE.
Gilles released last week transportpce-models artifacts for Cl-SR2, and is planning to release transportpce Cl-SR2 artifacts tomorrow
Status on transportpce-models changes merged since last meeting:
Status on transportpce changes merged since last meeting:
Sprint 31 started at the end of the session
Status on transportpce changes merged since last meeting:
"Remove getNode method from OlmUtils": uses get node method of PortMapping rather than creating a redundant one in OLM Utils.
Status on transportpce-models changes merged since last meeting: all changes are associated with the integration in Cl-SR1, and bump of upstream dependencies to Cl-SR2
Status on transportpce changes merged since last meeting:
Sprint 30 shall be finished. We proposed during the meeting to organize the demo next week after the regular tpce meeting. The sprint demo can be recorded. Please contact Gilles if you can not attend and expect it to be recorded or if you prefer that we reschedule it.
