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.

RFC 3257              SCTP Applicability Statement            April 2002

1 Introduction

   SCTP is a reliable transport protocol [RFC2960], which along with TCP

   [RFC793], RTP [RFC1889], and UDP [RFC768], provides transport-layer

   services for upper layer protocols and services.  UDP, RTP, TCP, and

   SCTP are currently the IETF standards-track transport-layer

   protocols.  Each protocol has a domain of applicability and services

   it provides, albeit with some overlaps.

   By clarifying the situations where the functionality of these

   protocols are applicable, this document can guide implementers and

   protocol designers in selecting which protocol to use.

   Special attention is given to services SCTP provides which would make

   a decision to use SCTP the right one.

   Major functions provided by SCTP can be found in Appendix A.

1.1 Terminology

   The following terms are commonly identified in this work:

   Association: SCTP connection between two endpoints.

   Transport address: A combination of IP address and SCTP port number.

   Upper layer: The user of the SCTP protocol, which...
