Ah, the 'but security, unlike transport,  is actually important'
argument.

Having seen subscribers to that philosophy unsuccessfully attempt to
design
transport protocols (and raise the MD5 issue repeatedly, because it's
considered a security issue, and they're at home with security), I would
argue
that there is a lack of appreciation and understanding  of the nuances
of
transport protocol issues in the IETF. Reliability, implications of the
end-to-end protocol, feedback loops...
<snip>
But watching security people make a hash of transport protocol
design really isn't fun. That and the lack of transport expertise
concerns me.

<tp>
We are not talking of transport protocol design - SCTP, DCCP,  ... -
but of Congestion Control design.  The question is can we do with a
Transport Area Director whose congestion control skills are limited; I
am suggesting we can, because of all the work over the years in
congestion control and the relative stability of the topic.

Transport matters, congestion control matters, I am just suggesting that
the latter is not developping so much that we need an AD who is abreast
of the research in it.
