Anoop,

Thanks, I'll discuss these suggestions with my co-authors. Also, now that
we've requested WG LC, Loa may want to treat this as a last call comment.

Your first comment isn't quite correct, since draft-ietf-mpls-sfc only
replaces some of the functions of the NSH. For example, there's no
packet-by-packet metadata.

Cheers,
Andy
