Hi Bob, I support the issue being picked up by IETF. What can be done within the bounds of IETF responsibility should be done. If ECN is seeing deployment, especially ECN support for IP over VLAN over IP/MPLS may be of interest. Further, ECN over LTE radio Access may be relevant (but my experti

Bob, I was thinking that it would be good to add the following clarifications: Given a suitable marking scheme ECN provides for the removal of nearly all congestion loss and it reduces delays for two main reasons: i) It avoids the delay when recovering from congestion losses, which particula

I do support this work going forward. I do understand Joe's position/desire and while it would be preferable to have a comprehensive document, I think draft-briscoe is useful by itself. FYI, Joe's draft can be found here http://tools.ietf.org/html/draft-ietf-intarea-tunnels-00 Thanks Suresh

Piers, I tried to state exactly how ECN can benefit (2nd para of intro below), rather than make overblown claims. You seem to be saying I didn't succeed? I can't see how to do any better. Suggestions? /\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\ ECN

Hi Bob, I took a brief look at the draft and it's clearly useful work. One thing that could do with clarification in the Introduction is that ECN - by itself - doesn't necessarily lead to low loss and delay - it should be made clear that it reflects the marking approach of the underlying scheme
