This document describes the usage of Service Codes by the Datagram
Congestion Control Protocol, RFC 4340.  It motivates the setting of a
Service Code by applications.  Service Codes provide a method to
identify the intended service/application to process a DCCP
connection request.  This provides improved flexibility in the use and
assignment of port numbers for connection multiplexing.  The use of a
DCCP Service Code can also enable more explicit coordination of
services with middleboxes (e.g., network address translators and
firewalls).  This document updates the specification provided in RFC

This document is a product of the Datagram Congestion Control Protocol Working Group of the IETF.

This is now a Proposed Standard Protocol.
