[mpls] Re: Working Group Last Call on draft-ietf-mpls-mna-hdr (2nd WG call)

["Zafar Ali (zali)" <[e-mail]>]

Dear chairs and the WG,

I agree with Matthew.
This is a major change to the MPLS data plane.
Only one academic implementation is not enough to publish a Standards Track hardware change.
The idea that we should publish premature ASIC change just because the current WG charter allows us to do so is quite dangerous.
The assumption that reserved flags will magically cover the part of the solution for which the workgroup has not yet adopted the work is equally dangerous.
Like many other WG participants, I failed to see the need to rush the work.

Thanks

Regards … Zafar

Hi Tarek

I’ve read the latest version of the draft and it is clear and well written.

The draft specifies some extensions to the MPLS data plane that fundamentally augment the way MPLS works, and provides new ways to alter the forwarding of MPLS packets. Although there was one experimental implementation which was very much appreciated, there doesn’t seem to have been any public attempt to survey the community for other implementations. Implementation might be a bit difficult because there isn’t even an early IANA allocation of the MNA bSPL . I appreciate that the MPLS WG has not traditionally put an implementation requirement on drafts, but given that MNA is making changes or additions to a data plane that has been deployed at the heart of the Internet for several decades it might be good to gain more implementation experience before publishing this draft on the Standards Track.

Matthew
