SG15/12 liaision on T-MPLS

The ITU SG15/12 has responded to our liaison
on T-MPLS.

This is posted at

https://datatracker.ietf.org/public/liaison_detail.cgi?detail_id=239

in addition they have CCed us on the response
to the MFA

https://datatracker.ietf.org/public/liaison_detail.cgi?detail_id=238

since this contains some notes of clarification that
are of interest to us.

We also expect to be CCed on the response to MPLS,
but this is still in the ITU approval. I will let
the WG know when I see the MPLS LS.

These liaisons contain a request that we review
the new text of g-8110-1_ar-v2.doc by 1-August to ensure
that our concerns have been addressed.

If anyone has any concerns with the text please let me know
and I will collect them together and respond on behalf of the
PWE3 WG.

[Fwd: Re: Congestion Control note to WG]

At the IESG review of the PWE3 ATM draft there were concerns
raised that although we make reference to a congestion avoidance
mechanisms in RFC3985 and in the various encapsulation drafts, we
have taken no steps to design one. This resulted in a blocking
DISCUSS being placed on the ATM work.

We have reached an agreement with the IESG, and in particular
with the transport ADs that the ATM draft will be unblocked so long as
we make a diligent attempt to design a suitable congestion avoidance
mechanism for PWE3.

As a reminder of the past, the PWE3 WG was started in the transport
area explicitly to ensure that we took into account the congestion
issues. Whilst we were under the management of the Transport Area
Directors section 6.5 of RFC3895 was written to scope the 
congestion problem in the PWE3 context.

To move this forward the chairs propose the following:

draft-rosen-pwe3-congestion-0x.txt

has be resubmitted with a view to using this as the basis of
either a problem statement/framework for this work, or as
the home of the description of the mechanism.

We will discuss this topic in Montreal, but I think that we need
to get a problem statement/framework to PWE3 WG draft status
within the very near future to demonstrate that we are upholding
our side of the bargain.

RE: [Fwd: Re: Congestion Control note to WG]

Sewart,

	Assuming Eric Rosen is willing to do this, I support this
proposal.

Thanks..

Matthew, can you make available via the PWE3 meetings page
and then post an updated agenda to the list with a pointer
included?

Thanks!
