Hi all,

Please note that I was reviewing the SFC architecture draft, see below, and I have a question:
http://www.ietf.org/id/draft-ietf-sfc-architecture-02.txt


Can you please let me know if the current version of the SFC architecture 
allows the use of different Service Function Chaining Header formats?

These formats and their analysis can be found in Section 5 of the following draft:

http://www.ietf.org/id/draft-boucadair-sfc-design-analysis-03.txt


If that is not the case, please elaborate why.

Best regards,
Georgios
