Re: [Lime-oam-model] OAM Model analisys. First cut

Hi Qin,
I believe that LIME charter is not to develop new OAM tools but to work on OAM data model that is relevant to all or some OAM models. If some OAM models do not have some of functions we find in other models, then we can flag that and discuss but in other group. The table you find in my writing is only start of what OAM model analysis may look like. I’d like the team to review it and help with comments and suggestions to extend the table. Then we can come to informed decision on what is common among IETF OAM models and discuss how useful data model of that common set may be.

                Regards,
                                Greg

Greg:
What conclusion do you make from this analysis? Do you want to make BDI and FDI being supported as common OAM function? Or do you want to make linktrace and loop back layer independent? Aren’t linktrace and loopback Ethernet specific functions?
I think the example you give in the table 1 gets complete alignment with the Table 4 in the section 5.2 of RFC7276.
[cid:image001.jpg@01D04071.5BF724F0]
That is to say Continuity Check, Connectivity Verification, Path Discovery, Performance measurement are common OAM functions for the all the OAM technologies.
Besides Common OAM functions, we also have fault domain, test point, addressing, technology type, sub technology type, specific layer. They are all common things
for all the OAM technologies.

Dear All,
apologies for belated update. Attached please find first cut of the proposal for approach to OAM Model comparison and example of it being used.

Your questions, comments, suggestions always welcome and greatly appreciated.

                Regards,
