Subject: [sfc] Network and service platforms

Reading through network service header draft and SFC architecture draft I am wondering about the meanings network and service platforms.

The architecture document mentions that "the collection of SFFs creates a service plane... " where SFs reside. The nsh draft defines network platform context and service platform context. Obviously service plane equates with service plane? That is, the service platform context is consumed by SFF,  SFC and the SFC-proxy.

Network platform context is then left for SFC NFs?

If that is the case, maybe you state that in the nsh document and define the mentioned platforms in the arch doc?

One more question. How does a SF communicate its changed  state to the classifier or a SF that precedes it in the chain. This would useful to LB SF but also others may benefit from it.
