Hello Daniel/Qin,

Greetings for the new use-case document.
I would like to raise another important use-case which is actually a combination of two cases described in the draft.

In a given network when looking end2end you will have at least one IP/MPLS domain and one SFC domain.
The following use-case figure may help understanding this (sorry for the simple graphic :)).
The overall service is provides from the CE device to the other "end" of the network traversing several domains/segments.

It is beneficial to be able to see the service as a whole from an OAM perspective and maintain the end to end chain.
This is of course in addition to the OAM for each segment, done independently.

IMO, we should think how to integrate the two parts or at least convey some information from segment to segment.



2.4.  IP/MPLS OAM combined with L4-L7 OAM

<--------------------------------------------------------------------------- End to End Service ------------------------------------------------------------------------------------------>
<----------------------------------------IP/MPLS domain-------------------------------------> <----------------------------------------SFC domain--------------------------------->
