The IESG has approved the following document: - 'UDP Encapsulation of SCTP Packets for End-Host to End-Host Communication' (draft-ietf-tsvwg-sctp-udp-encaps-14.txt) as Proposed Standard This document is the product of the Transport Area Working Group. The IESG contact person is Martin Stiemerling. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-tsvwg-sctp-udp-encaps/ Technical Summary This document describes a simple method of encapsulating SCTP Packets into UDP packets and its limitations. This allows the usage of SCTP in networks with legacy NAT not supporting SCTP. It can also be used to implement SCTP on hosts without directly accessing the IP-layer, for example implementing it as part of the application without requiring special privileges. Working Group Summary There was consensus to adopt this as a WG document alongside other drafts in the Behave WG on NAT/NAPT traversal and agreement by the WG to publish this. Document Quality This draft is implemented in FreeBSD and released in 9.1. It is also implemented in the Mac OS X kernel implementation (a port of the FreeBSD one), which is available from http://sctp.fh-muenster.de and also available in the userland stack based on the FreeBSD kernel implementation. Personnel Gorry Fairhurst (gorry@erg.abdn.ac.uk) is the document shepherd. The responsible Area Director is Martin Stiemerling (martin.stiemerling@neclab.eu).
