Datagram Congestion Control Protocol Simultaneous-Open Technique to Facilitate NAT/Middlebox Traversal

Overview

RFC 5596, “Datagram Congestion Control Protocol Simultaneous-Open Technique to Facilitate NAT/Middlebox Traversal”, is a Proposed Standard document published in September 2009 by G. Fairhurst. It updates RFC 4340. The canonical text is published by the RFC Editor.

Abstract

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. [STANDARDS-TRACK]
