The IESG has approved the following document: - 'An MPLS-Based Forwarding Plane for Service Function Chaining' (draft-ietf-mpls-sfc-07.txt) as Proposed Standard This document is the product of the Multiprotocol Label Switching Working Group. The IESG contact persons are Alvaro Retana, Martin Vigoureux and Deborah Brungard. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-mpls-sfc/ Technical Summary This document describes how Service Function Chaining can be achieved in an MPLS network by means of a logical representation of the NSH in an MPLS label stack. That is, the NSH is not used, but the fields of the NSH are mapped to fields in the MPLS label stack. It does not deprecate or replace the NSH, but acknowledges that there may be a need for an interim deployment of SFC functionality in brownfield networks. Working Group Summary The processing of this document have been very smooth and the support from the working group is strong. Document Quality We do not currently have any definite information on existing implementations, an Implementations poll has been started and the write-up will be updated as soon as we get new information. There has been indications from vendors that they intend to implement this specification. We also have a strong interest from operators to have this implemented. No special types of reviews is necessary. Personnel Who is the Document Shepherd for this document? Loa Andersson Who is the Responsible Area Director? Deborah Brungard
