Hi All,
OK, I'll accept the apparent consensus and make the DCCP header the same
format in both encapsulations. Note that a DCCP implementation is still
going to need to know whether this came in with UDP encap or STD encap
-- the checksum processing needs to be different at least.

DCCP wouldn't need to care about checksums if we had a generic
encapsulation scheme, such as the one we have been discussing on the TSV
list, the Generic UDP Tunneling scheme GUT.

Hi Jukka,
Well, I guess one of us misunderstands something, because it looks to me
like GUT doesn't work. Taking your example in section 3.3 of the draft:
We start out with a DCCP packet encapsulated in IP as:
Dest addr (DA): B
Src addr (SA): A
DCCP Ports: E and F (I assume
Yes, that's right. Except that GUT itself recalculates the checksum
before the packet hits the DCCP receiver. Thus, the UDP-encapsulated
DCCP flow never needs to do anything - it never even sees that GUT was
there.
