Hello, May I ask a question? For me as a user of DCCP, - I am not an expert in this area - it is unclear how to set up a bidirectional RTP connection with DCCP-UDP or DCCP-STD. Do two DCCP connections have to be opened - one for each direction -, or did I missed some RFCs or drafts describing how to negotiate it with SDP?

The major changes are using the standard DCCP header and not allowing the use of partial checksums. Feedback appreciated.

This encapsulation will allow DCCP to be carried through the current generation of Network Address Translation (NAT) middleboxes without modification of those middleboxes. The IETF Secretariat.
