hi, yuanlong
Please refer to comments entitled with [Xiaobing]
On the contrary, the description in Section 5 of OIF FlexE 2.0 is more specific: "The FlexE Shim is the layer that maps or demaps the FlexE Clients carried over a FlexE Group" and "Each FlexE Client has its own separate MAC, Reconciliation Sublayer, and xMII above the FlexE Shim which operate at the FlexE Client rate." The relationship of a FlexE Client, FlexE Shim and its FlexE Group is rather fixed according to this description.
[Xiaobing] In my opinion, those descriptions exactly support the flexibility between FlexE clients and a FlexE group.
In Rob’s YANG module, the modeling of “client-interface” (similar to flexe-client-list in draft-jiang) actually has an attribute “name if:interface-ref”, which can reference to any internal interface (as described in 7.2.1, unclear what parameter is to be managed yet) or any Ethernet PHY (as described in 7.2.2).
Therefore, it provides the flexibility to support any type of FlexE Client bit-stream (i.e., 64B/66B encoded bit-stream).
Otherwise, if FlexE Client is modeled as standalone and could be associated with different FlexE Groups (assuming there is such a support in the data plane), we can hardly configure anything when its FlexE Group is undetermined, since:
[Xiaobing] The configuration of a FlexE client and group can be performed at different time. Just image you first establish a FlexE group without carry any FlexE client, and then configure some FlexE clients over that group.
