Re: [sfc] Question About Path Selection in SFC

I am not sure I understand the question.

The operating model for the SFC Data Plane is that control operations 
decide what paths they wish to have (this can be centralized or 
distributed control).  These paths are then represented by

1) Service Function Path IDs, which are mapped at each SFF, using the 
Service Index, to the specific service functions and the next SFF the 
packet is to be sent to.

2) Initial classifiers (and where needed in-sequence reclassifiers) 
which assign service function path IDs and Indices to packets.

So creating a specific service function path using NSH is done by 
control assigning the needed ID and creating the needed state in SFF and 
classifiers.

Yours,
Joel
