Hi Stewart,

I still have to read more about DetNet, but I am not sure if there is a real contention with PALS.

My understanding of 0000 nibble in PW control world is that it is only to prevent a transit node from mistaking the payload as IP. Is it supposed to indicate that any payload starting with 0000 is PW payload? I hope not.

Use of 0000 nibble in GDFH is also just to prevent transit nodes from mistaking it as IP. It does indicate it is GDFH. It should be able to co-exist with PW CW.

Thanks.
Jeffrey

Stewart, all,

I apologize for not responding to this in time. I some how accidentally moved a few wg mailing list email folders to a place where I could not see so I missed all the discussions.
Let me catch up all the emails and then reply.

Thanks.

[External Email. Be cautious of content]


Thank you Jeffery

Please see the note that I sent about iOAM who also want to sit after BoS … and both of you want the same space that PALS and DetNet is already using.

We plan to have a joint session on this hosted by PALS at the next IETF, but I think we also need to include the iOAM people.

This has scope to get very messy as we find new candidates for BoS metadata so we really need to take a holistic position to ensure the future health the MPLS protocol.
