However, I would really like to reinforce the point from another note. There are quite a few contexts where the ability to run a sensible transport directly over IP is indeed very useful. For example, the ForCES working group scope is limited (by chart) to the case where the control element is near the forwarding element. I am not worried about there being a NAT between those. So SCTP or DCCP over IP is very relevant. Yours, Joel M. Halpern Jonathan Rosenberg wrote: > I wrote this because of a discussion that happened during behave at the > last IETF meeting in Vancouver.
