| Potential synergy with ORAN/LF/ONAP | Tracy Cagatay | - https://www.o-ran.org/ - modeling work for open disaggregated RAN, open APIs and whitebox designs
- note adopts also work from XRAN
- welcoming people to join and participate in efforts
- https://www.onap.org/
- Several separate domain-specific modeling activities - what can we do to help coordinate work, so that we lead to compatible models?
- Operators want compatible models across vendors, domains and organizations for interoperability
- ease of version-control and rapid release-management are very much needed
- ONF/CIM methodology of common core model plus conditional packages would allow commonality plus flexibility
- Holistic e2e view
- Nigel: notes previous 3GPP/TMF joint work - TMF work in turn is one basis for ONF/CIM work, so there is existing relationship with 3GPP SA5
- TMF has adopted ONF Core Model back into their networking model and may feed back into 3GPP modeling
- one area to adopt is the decoration methodology
- ONF Core Model has physical equipment model, modeling of constraints, control, generalized processing (goes beyond transport)
- TAPI is pruned and refactored from the Core Model
- Cagatay - TMF not directly involved - Nigel - work has moved on to other groups - Tracy - TMF supportive of bigger picture
- Martin - pattern is very important beyond the model itself, very helpful from a development perspective, allows much quicker innovation and demonstration
- Nigel - note Core Model also published by ITU-T
- Karthik - federated approach, respecting spaces of each participating organization (as in interactions with ITU-T, e.g., on photonic modeling)
- Tracy - first step could be to take XRAN FH M-Plane work, bring it together with ONF CIM, ONAP modeling to make this more generic
- Note M-Plane spec is already public and can be downloaded publicly (needs registration) - http://www.xran.org/resources/
- similar open specs available from ONAP
- allow for more potential types of splits in future
- Good cross-group relationships - will need to work around any organizational issues
- ORAN working on what can be made available
- set up some open joint discussion
- look at, e.g., how M-Plane work relates to an overall OAM architecture - what is architecture in ONF work
