Abstract

   This document provides a high level introduction to the capabilities
   supported by the Stream Control Transmission Protocol (SCTP).  It is
   intended as a guide for potential users of SCTP as a general purpose
   transport protocol.

1. Introduction

   The Stream Control Transmission Protocol (SCTP) is a new IP transport
   protocol, existing at an equivalent level with UDP (User Datagram
   Protocol) and TCP (Transmission Control Protocol), which provide
   transport layer functions to many Internet applications.  SCTP has
   been approved by the IETF as a Proposed Standard [1].  The error
   check algorithm has since been modified [2].  Future changes and
   updates will be reflected in the IETF RFC index.

   Like TCP, SCTP provides a reliable transport service, ensuring that
   data is transported across the network without error and in sequence.
   Like TCP, SCTP is a session-oriented mechanism, meaning that a
   relationship is created between the endpoints of an SCTP association
   prior to data being transmitted, and this relationship is maintained
   until all data transmission has been successfully completed.

   Unlike TCP, SCTP provides a number of functions that are critical for
   telephony signaling transport, and at the same time can potentially
   benefit other applications needing transport with additional
   performance and reliability.  The original framework for the SCTP
   definition is described in [3].
