=================
Linux Kernel SCTP
=================

This is the current BETA release of the Linux Kernel SCTP reference
implementation.

SCTP (Stream Control Transmission Protocol) is a IP based, message oriented,
reliable transport protocol, with congestion control, support for
transparent multi-homing, and multiple ordered streams of messages.
RFC2960 defines the core protocol.  The IETF SIGTRAN working group originally
developed the SCTP protocol and later handed the protocol over to the
Transport Area (TSVWG) working group for the continued evolvement of SCTP as a
general purpose transport.

See the IETF website (http://www.ietf.org) for further documents on SCTP.
See http://www.ietf.org/rfc/rfc2960.txt

The initial project goal is to create an Linux kernel reference implementation
of SCTP that is RFC 2960 compliant and provides an programming interface
referred to as the  UDP-style API of the Sockets Extensions for SCTP, as
proposed in IETF Internet-Drafts.

Caveats
=======

- lksctp can be built as statically or as a module.  However, be aware that
  module removal of lksctp is not yet a safe activity.

- There is tentative support for IPv6, but most work has gone towards
  implementation and testing lksctp on IPv4.
