Re: IP Traffic Engineering

[Robert Raszuk <[e-mail]>]

Hi Adrian and Lou,

Many thx for your suggestion.

Reading charter of TEAS it does seems like a good fit for the IP TE part.
What is however not in the TEAS charter is concept of network functions
which is the second part of the solution natively embedded in the proposed
architecture from day one (IP TE*+NP *part).

I think I will not hurt anyone to submit it to TEAS. I guess we can keep
-00 also in RTGWG for now.

I guess it will be up to chairs and ADs of those two working groups to
decide which one should "own" this type of hybrid work.

Btw looking at TEAS charter I found a bit artificial scoped coordination
with IDR limited to BGP-LS.

"- With the IDR WG on the use of BGP-LS in TE environments."

In my specific case I do plan to use other BGP extensions as possible
alternatives to distribute the path+function information around. But I am
not defining any new extensions (only reusing as is
draft-ietf-idr-segment-routing-te-policy)
so this is not a stopper for me.

Many thx,
Robert.
