See RFC 5762 for the standard DCCP case.

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?

With best regard,

Christian

Hi All,

I've created a new version of dccp-udpencap (see below).  The major
changes are using the standard DCCP header and not allowing the use of
partial checksums.  Feedback appreciated.

A new version of I-D, draft-ietf-dccp-udpencap-01.txt has been
successfully submitted by Thomas Phelan and posted to the IETF
repository.

Filename:        draft-ietf-dccp-udpencap
Revision:        01
Title:           Datagram Congestion Control Protocol (DCCP)
Encapsulation in UDP for NAT Traversal (DCCP-UDP)
Creation_date:   2010-06-24
WG ID:           dccp
Number_of_pages: 11

Abstract:
This document specifies an alternative encapsulation of the Datagram
Congestion Control Protocol (DCCP), referred to as DCCP-UDP.  This
encapsulation will allow DCCP to be carried through the current
generation of Network Address Translation (NAT) middleboxes without
modification of those middleboxes.
