	Title           : The DCCP Service Code

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 
4340.
