Housekeeping:
OSC SMO Meeting Series: Reminder from previous weeks:
- OSC SMO calls now move to its own time slot - Thursdays
- See OSC RSAC Calendar: https://wiki.o-ran-sc.org/display/RSAC/calendars
- (Note this meeting to open to anyone, including non-ORAN members)
- We will maintain this slot for ONAP Alignment, and try flag issues/question to/from SMO meetings.
- See OSC SMO Project meeting notes
NOTE: DST Changeover in coming weeks!
- See above & Keep a close eye on the calendars!
OSC Project roundup:
News from OSC TOC call this week
- https://wiki.o-ran-sc.org/display/TOC
- We all remain somewhat confused about copyright..... will update when we know more
- Integration project PTL election completed: James from CMCC elected!
NONRTRIC (John Keeney)
- Working mainly on Helm chart updates ... see also below
SIM (Alex Stancu)
- Topology service available!
- TAPI topology simulator. (See below)
- Image: nexus3.o-ran-sc.org:10004/o-ran-sc/smo-nts-ng-topology-server:1.3.6
OAM (Martin Skorupski)
- Working on helm charts.
- Struggling with licensing issues. (See below)
O-DU (Hariom Gupta )
- Hariom GuptaStill figuring out if 3GPP Yang model can be used / implemented.
Topology Models:
- No model suits everyone
- TAPI model is quite abstract / domain independent - basically functions & endpoints ( edge-point, interface, logical termination point, connection points etc)
- Simulator/Usecases considers CUs, DUs, RUs, & their location
- Topology model loaded/configured at start time (JSON/XML). Made available using TAPI Netconf model. (Netconf server)
- @All - Discussion:
- Cell/Neighbour-Relation? Not explicitly modeled ... but would it be a function, connection, logical grouping, parameter?
- All valid for different usecases! Everyone has their own topology model for their own use case!
- TAPI is very abstract, so a good starting point for more specific topology models.
- Discussion continue in ONAP modelling work.
- Cell/Neighbour-Relation? Not explicitly modeled ... but would it be a function, connection, logical grouping, parameter?
- Is ANR (Automated Neighbor Relations) supported in O-RAN?
- Not O-RAN specific ... feature/usecase that can be implemented in various ways in 4g, 5g, etc ... Centralized, Distributed, Hybrid, in xApp, etc....
ONAP SMO deployment options
- Sebastien: Pull Request on OSC it/dep repo for existing SMO Deployment package - will overwrite existing version
- https://gerrit.o-ran-sc.org/r/c/it/dep/+/6860
- It very big though so will take some time.
- John Keeney & Sebastien should talk offline about changes from original, and proposed changes to NONRTRIC helm charts (also in progress)
- Should also now include new INT PTL
- David Johnson Mini deployment in POWDER lab seems to be working well! Will also look at SMO Deployment here & feedback.
- Sebastien: Also working on OOM changed (DCAE/VES Collector config for SDNC)
- Sebastien: Also has an issue with O-RU-use case App ... issue with HTTPS .... Python issue?
Copyright & Licensing
- SCCL:
- Recent "Special TOC Call" about licensing, but was not SCCL recorded
- SCCL does not address 3GPP license issue - Issue continues as before
- O-RAN Alliance will try persuade 3GPP to use SCCL ... but progress stalled.
- SCCL is currently only for O-RAN Alliance material - to be agreed to by anyone using/redistributing these specs
- OSC is a first mover to put procedures in place
- SCCL is copyright only - IPR licensing is a seperate issue and not addressed
- SCCL is not an open-source license
- We are making some progress understanding SCCL
(but we're not there yet!)
- Can SCCL specs be redistributed freely?: No.
- Recent "Special TOC Call" about licensing, but was not SCCL recorded
- 3GPP:
- Surely there is potential to request a PoC/Demos/non-Commercial derogation from 3GPP
- We need to keep pushing.
- Tracy Van Brakle IIRC 3GPP does allow use for demos/poc/exhibitions ? Will check up on this! This should be enough for our requirements.
Simulators
Q&A
Copyright & Licensing
- SCCL: Any open source project can reuse SCCL artifacts - if they abide by by process for that license
- Note SCCL is not an opensource license!
- ONAP may want examine/reuse? the work in OSC for supporting SCCL?
- Long discussion about 3GPP licensing:
- Open/Public != OpenSource != Free
- Try to keep functions model-driven as a much as possible so loosely coupled from copyrighted specs/model, so specs are not reproduced/re-distributed.
- But this is not possible for the actual function encoding the model (e.g. a netconf server & Yang model) or function simulators/emulators, or POCs
- We see no clear path forward for this very long running issue.
- We need to be conservative until we have clear guidance / path forward.
- Unwilling to risk copyright or IPR infringement
- Likely a common-sense reuse approach is possible - with no commercial aspect involved - but we cannot assume this.
- SCCL: Any open source project can reuse SCCL artifacts - if they abide by by process for that license
