Questions/Clarifications

• VES Disaggregation

  • Does DMaaP support include publishing to Kafka bus? While no particular use case was identified for how a DMaaP publisher to Kafka bus would be needed, @David Kinsey [AT&T]suggested that it should be implemented from a feature completeness perspective. @Kiran Ambardekarand team to evaluate what it will take to implement a publisher in addition to a consumer.

  • Is there a requirement to support authentication of entities that can write/read to/from the Kafka bus? @John Keeney (Ericsson EST)reminded us that authentication should be looked at more holistically than just from a VES perspective. As such, E-release will support encryption, but will support a single user/entity in writing/reading to/from the Kafka bus.

  • Does Kafka bus need to support REST APIs? @David Kinsey [AT&T]and others did not believe that REST API support was needed. That applications should use the native APIs exposed by Kafka bus.

• VES E-Release requirements

  • The current implementation of VES supports PM metrics in the form of measurement events that are streamed as VES events to a VES collector. It does not support the file or Websocket (with ASN.1 encoded) event format. @Hariom Guptaneeds to consult with @Former user (Deleted)to decide if O-DU can support PM metrics in the form of VES measurement events for the E-release. Even though this is not part of the 3GPP or O-RAN specification, this effort would a trial to prove that such events can also be streamed as VES events, and in doing so eases implementation. Separately, @David Kinsey [AT&T], @Martin Skorupski, @N.K. Shankaranarayanan, @Mahesh Jethanandaniand others will work on a CR to influence O-RAN Alliance to adopt VES streaming of measurement events as a standard.
