Technical Summary 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. Working Group Summary The WG consensus process for this document was uneventful. Document Quality There are existing implementations of DCCP that utilise Service Codes. Some implementors were involved in the WG discussion. Compliance of the implementation with the final Spec. has not been verified. No interops were performed. Personnel Lars Eggert (firstname.lastname@example.org) reviewed this document for the IESG.
