SD-RAN 1.3 Released

[Saurav Das]

Hi all,

Today we released SD-RAN 1.3 with updated versions of our micro-ONOS based nRT-RIC, xApp-SDKs, new xApps, whitebox LTE CU/DU/RU solution, and sdRan-in-a-Box (RiaB).

The highlights of this release include two new use case implementations - xApp based Mobile Handovers and RAN Slice Management - as well as the ability to run multiple instances of the E2T microservice for HA and horizontal scalability.

As before, we also continue to upgrade the RIC platform to the latest O-RAN specifications  -  this release includes E2 AP 2.0 support while maintaining support for the previous version 1.01.

A helpful listing of the use-cases, xApps, SMs and their support in this release on various platforms is shown below

Dear ONF Team:

     Regarding to  E2AP 2.0, I can only find the latest E2AP spec version is v1.01(O-RAN.WG3.E2AP-v01.01.docx) from  O-RAN ALLIANCE Specifications — O-RAN ALLIANCE. Where can I download E2AP 2.0?

     Many thanks!

Dear ONF team,

   Many thanks for your clarification.

Another question is how to get the source code for release 1.3, I can not find rel-1.3 branch from onosproject/sdran-helm-charts: Helm charts for SD-RAN (github.com). Which branch shall I pick up?

Thanks!

Hi Jing,

We branch when we need to (lazy branching).

Otherwise we just use tags - https://github.com/onosproject/sdran-helm-charts/tree/sd-ran-1.3.0

Simple deployment directions here: https://docs.sd-ran.org/master/release_notes/sdran_1.3.html#deployment

Thanks

Dear ONF team,

Thanks for your timely reply. One more question regarding to release 1.3:

Does release 1.3 support following functions defined in <O-RAN.WG3.RICARCH-v02.00>? 

6.2.3   Conflict Mitigation (Seems not support?)

6.2.4   Messaging Infrastructure(fully support?)

6.2.5   Security (Seems not support?)

6.2.6   Management Services:

6.2.6.1  Life-Cycle Management of xApp:

"- Resource management (RM): It does comprehensive resource provisioning/control for xApps on Near-RT RIC as well as monitors their latency and resource consumption characteristics to see if individual xApps meet their latency requirements. It may trigger alarm event when they miss the critical latency requirements.

- Termination of xApps: It terminates a running xApp if the xApp is no longer needed. The resource used by the xApp will be released."

---------Is above requirement supported? If yes, in which component?

6.2.6.2  FCAPS Management of Near-RT RIC(Seems not support?)

6.2.7.3  O1 Termination(Seems not support?)

7.6    SDL APIs(Seems not support?)

 Many thanks!
