This document specifies an update to the Datagram Congestion Control
Protocol (DCCP), a connection-oriented and datagram-based transport
protocol.  The update adds support for the DCCP-Listen packet.  This
assists DCCP applications to communicate through middleboxes (e.g., a
Network Address Port Translator or a DCCP server behind a firewall),
where peering endpoints need to initiate communication in a near-
simultaneous manner to establish necessary middlebox state.
