This document describes the Simple Control Transmission Protocol
(SCTP). SCTP was designed to transport PSTN signalling messages over
IP networks, but is capable of broader application.
SCTP is an application-level datagram transfer protocol operating on
top of an unreliable datagram service such as UDP. It offers the
following services to its users:
- acknowledged error-free non-duplicated transfer of user data
- application-level segmentation to conform to discovered MTU size
- sequenced delivery of user datagrams within multiple streams,
with an option for order-of-arrival delivery of individual
datagrams
- optional multiplexing of user datagrams into SCTP datagrams,
subject to MTU size restrictions
- enhanced reliability through support of multi-homing at either or
both ends of the association.
The design of SCTP includes appropriate congestion avoidance behaviour
and resistance to flooding and masquerade attacks.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
