Re: [mpls] Working Group Adoption Poll on draft-song-mpls-extension-header

I support WG adoption.

>From the MNA Polls by Loa this past summer..

I agree that the Framework draft should be solution independent and say
that a packet carrying ancillary data can use one or both PSD or ISD as
both are viable options and should be part of the overall MPLS DT solution
strategy.

I agree it’s up to the solutions documents such as this draft specifying
the network action to specify which method to be used in this case PSD and
for which ancillary data, OAM etc.

I support this draft’s solution for PSD using PAH.

This draft has parity to IPv6 extension headers using the learnings from
IPv6 EH concept and now with its application to the MPLS data plane to
provide similarly MNA extensibility and scalability.

With the learnings from IPv6 extension headers issues addressed by 6MAN Bob
Hinden to limit the number of HBH options TLVs to one option to be
processed in the fast path.  This same concept and learnings from IPv6 EH
 for performance gain  is applied to this draft to pack only one MNA action
in the extension header to be processed and avoid packing multiple TLVs
into the extension header for improved performance.

https://datatracker.ietf.org/doc/html/draft-hinden-6man-hbh-processing-01

However, as well different from IPV6 RFC 8200, the MPLS data plane
requirements for in flight packet modifications add/delete/change, the MNA PSD
solution provides as well flexibility and backwards compatibility solution
for the MPLS data plane.

Thank you
