Re: [PWE3] Updates to WG milestones

[<[e-mail]>]

I don't see anything that looks like congestion control or cooperative behavior in
the face of congestion in that draft - IMHO, it looks like it's aimed at bandwidth
provisioning (committed rate + max burst rate/size).

OTOH, I think at least Yaakov Stein and I are going to try take another run at
producing a draft on congestion considerations (e.g., what happens when a fixed
bandwidth IP pseudowire is mixed with congestion responsive IP traffic so that
the two compete for limited forwarding capacity, and what should be done about
it?), but we both have problems with our day jobs distracting us from IETF work,
so this won't exactly be quick ;-).

If this comes together, we should have at least a -00 draft for Paris, so I'd ask
that the congestion considerations WG LC milestone be moved out to sometime next
summer (or even September 2011).

Thanks,

Hi Mathew -
Comment on PW congestion consideration that is proposed for 'delete' from charter.

Was wondering if PW-QOS-signaling (http://tools.ietf.org/html/draft-shah-pwe3-pw-qos-signaling-02)
that proposed throttling from successor to predecessor PE (via feedback loop) is applicable to this charter??

Also, why proposed delete? No interest? p2mp difficulties?

Thanks,
himanshu

All,

We need to update the milestones that we have on the charter to reflect our current work items and the revised dates that we expect to complete them.

Please find below a list of the updates we propose for the milestones that are currently not marked as 'done'.

We have also added a few notes against some of the milestones.

Please can you send any comments to the PWE3 list before Friday 2nd December.

Regards,

Matthew & Andy
