Re: [dccp] port numbers and DCCP

[Allison Mankin <mankin at psg.com>]

Eddie,

Yes, port names are not a scarce resource, but they're also to some
extent imbued with meaning.  

Actually my proposed scheme has a big hole, because every TCP port 
has a UDP port in the current IANA registry.  So if someone wants to register
a TCP portname, they don't need to worry about the TCP version, just
register the UDP one. 

I simply disagree with the spec implying that it makes sense, FCFS, for
DCCP to register a portname such as "http" and port 80, which adds up
to saying DCCP is just fine for porting applications from TCP.  This 
is not good transport advice.

But I seem to be saying this for the third time...or fourth?

I look forward to your next email.

Allison
