Shepherd writeup
rfc7665-11

This architecture document is the product of the Service Function Chaining (SFC) WG in the IETF Routing Area.  The WG is chaired by Jim Guichard and Thomas Narten.  Alia Atlas and Adrian Farrell are the routing area directors, with Alia being the AD directly supervising this working group.

This document describes an architecture for the specification, creation, and ongoing maintenance of Service Function Chains (SFC) in a network.  It includes architectural concepts, principles, and components used in the construction of composite services through deployment of SFCs, with a focus on those to be standardized in the IETF.  This document does not propose solutions, protocols, or extensions to existing protocols as these will be addressed in other documents produced by the SFC WG.

Note that the selected architecture presents a model addressing the problematic aspects of existing service deployments, including topological independence and configuration complexity as laid out in the SFC WG problem statement document.

This document has been reviewed multiple times by many participants in the working group and has undergone several revisions to integrate all aspects requested of the SFC architecture.  The document is also the product of a merge of multiple previous documents. 

The document is in good shape, and the shepherd agrees with the chairs conclusion that it is ready for publication as an informational RFC.
