Abstract

   This document describes the applicability of the Stream Control
   Transmission Protocol (SCTP).  It also contrasts SCTP with the two
   dominant transport protocols, User Datagram Protocol (UDP) &
   Transmission Control Protocol (TCP), and gives some guidelines for
   when best to use SCTP and when not best to use SCTP.
