Internet Drafts (IDs) related to SCTP


This ID provides general considerations for SCTP and NATs.
This ID describes an SCTP aware NAT method.
This ID describes an SCTP tunneling over UDP for legacy NATs.

Additional Information

This ID describes a socket interface for SCTP. This describes two APIs different from the example API given in the SCTP specification.
This ID describes how SCTP in combination with the addIP extension can be used for providing a mobility concept.
This ID describes DTLS over SCTP.
This pages lists the SCTP numbers registered at IANA.

The sctplib Implementation

The SCTP implementation supports the current version of the protocol. It runs under Linux, FreeBSD and Mac OS X and supports IPv4 and IPv6. The software is a result of a cooperation between Siemens, the Computer networking technology group of the University of Essen and the Münster University of Applied Sciences.

Getting the Source

This is very easy via the download page.

Support via mailinglists

We will announce all new versions of the SCTP implementation on this list. So if you want to have an up to date version, subscribe to this list. You can not send any mail to it. It is only for announcements. Use the WWW interface for subscription.

This mailing list should be used for comments, bug reporting and all other things you would like to discuss with the other users or developers. Your mails are accepted only if you have subscribed the mailinglist. Use the WWW interface for subscription.
