[mpls] Re: Working Group Last Call on draft-ietf-mpls-mna-hdr

[Tianran Zhou <[e-mail]>]

Yeah, I can give some more detailed use cases.
On the other hand, how to achieve this?
“Several actions can share the same metadata if their descriptions are written up correctly.”
It’s great if existing MNA mechanism can support this.
And I hope this could be documented in the draft.

[WG chair hat: off]

Several actions can share the same metadata if their descriptions are written up correctly.

Why do you need a new format for this?

A specific proposal or use case would really help the discussion.

Hi John,

One packet may need multiple actions/opcodes.
The group format will indicate several actions can share the same metadata.

So, for what are the post opcode bits in each of the subsequent format C LSEs used?

Hi WG and Authors,


This draft proposed the 4 LSE formats with sequence: A-B-C-D.

I want to propose a new LSE format. Let’s call it C’ temporarily.

C’ is a kind of group, which can group several C formats.

So the sequence is A-B-C’-C-D.


This format can reduce the redundancy of several LSEs.

For example, if several LSEs have the same flow id, we can just put this flow id at the beginning of the group. And all the following LSEs in this group can use.


Best,

Tianran
