Ballot Text

Technical Summary

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
DCCP server behind a firewall, or a Network Address Port Translator),
where peering endpoints need to initiate communication in a near-
simultaneous manner to establish necessary middlebox state.

Working Group Summary

A copy of the last-call note was also sent to the BEHAVE WG list.
