Major Features

• TTP Command Line Tools: Allow for reading, parsing, verifying, printing and analyzing TTPs as read from JSON via an executable CLI jar file.
  • Flow Path Exploration (new in Beryllium) Also present in Lithium-SR2
• TTP Model: A YANG model for TTPs.
• TTP Database: A database of available TTPs using the YANG model.
• TTP Switch Augmentation: An augmentation for nodes in OpenDaylight to allow them to have zero-or-more supported TTPs and zero-or-one active TTP.

Target Environment

As per the general Beryllium release, i.e., a Java 7 or Java 8 JRE to run the tools and a Java 7 or Java 8 JDK for development.

Known Issues and Limitations

• The TTP YANG model does not match the ONF TTP JSON precisely. Exact details are documented in the TTP model YANG file.

Bugs Fixed in this Release

• Minor fixes to the OF-DPA 2.0 TTP json file.

Compatibility and Migration from Previous Releases

• The TTP model is the same as in the Lithium release so any migration and/or tools should continue to work.
• To migrate actual data, it is recommended that users back up their current TTP-related data, upgrade and then restore it like so:
  1. Do an HTTP GET to: http://localhost:8181/restconf/config/onf-ttp:opendaylight-ttps/onf-ttp:table-type-patterns/
  2. Store the result
  3. After upgrading do an HTTP PUT with the stored result and the same URL
• You can use the same process to backup and restore any data associated with a switch, but the exact URL will vary depending on the switch and it will have to be done on a switch-by-switch basis.

Deprecated, End of Lifed, and/or Retired Features/API

• None.
