Everyone,
Many thanks for your comments and discussion and apologies for the
delay in coming back to this!
I think a fair summary is that people who commented would support UDP
encapsulation for DCCP (and other middlebox-challenged transports),
but whether that should be hosted in TSVWG or here, and whether it is
better to aim for a common solution or do separate (but closely
aligned) drafts for different transport protocols needs to be thought
out. Note that there was discussion about the feasibility of a common
solution already in the Hiroshima meeting, in the TSVAREA session.
I take the feedback as a positive indication to continue the work on
dccp-natencap, but I think we should not take DCCP WG action just yet,
before getting clarity on the above questions. One possible way
forward would be this: the authors continue working on the DCCP and
SCTP encapsulations as separate drafts, but aiming to converge between
them as much as possible. For the DCCP draft, I think we got some
useful feedback for Tom to work on a revision. The two encapsulation
drafts could be discussed in the Anaheim IETF side by side (possibly
in the TSVWG meeting), for deciding about the next steps. Please let
me know if you don't like this plan.

Hello,
During the Hiroshima meeting last week some support (and some
concerns) was voiced about working on UDP encapsulation for DCCP,
with a suggestion to allocate an UDP port to be used for DCCP
encapsulation. To make this happen, it was proposed that we bring
back draft-phelan-dccp-natencap, for the WG to submit it for
Experimental RFC. Tom has now updated the draft and the refreshed
version can be found at http://tools.ietf.org/html/draft-phelan-dccp-natencap-03
With the above background in mind, I'm now looking for input on the
following questions:
a) in your opinion, should the DCCP WG start working on UDP
encapsulation for DCCP?
b) if yes, do you think draft-phelan-dccp-natencap is a good
starting point for this, and therefore should become a WG document?
In addition, please speak up if you have other technical comments
about the draft.
Thanks!
