Hi co-authors,

I wonder whether the NSH encapsulation would strictly follow the transport-independance principle as defined in the SFC architecture draft. If so, it's possible that the NSH would be transported over MPLS networks someday. As such, it's better to consider the first nibble issue associated with the current MPLS architecture from the beginning. I have not seen any text in this regard in this new version.

Best regards,
Xiaohu

A New Internet-Draft is available from the on-line Internet-Drafts directories.
 This draft is a work item of the Service Function Chaining Working Group of the IETF.

        Title           : Network Service Header
        Authors         : Paul Quinn
                          Uri Elzur
        Filename        : draft-ietf-sfc-nsh-01.txt
        Pages           : 43
        Date            : 2015-07-23

Abstract:
   This draft describes a Network Service Header (NSH) inserted onto
   encapsulated packets or frames to realize service function paths.
   NSH also provides a mechanism for metadata exchange along the
   instantiated service path.  NSH is the SFC encapsulation as per SFC
   Architecture [SFC-arch]
