Abstract

   The Stream Control Transmission Protocol (SCTP) is a transport
   protocol originally defined to run on top of the network protocols
   IPv4 or IPv6.  This memo document specifies how SCTP can be used on
   top of the Datagram Transport Layer Security (DTLS) protocol.  SCTP
   over DTLS is used by the RTCWeb protocol suite for transporting non-
   media data between browsers.

Status of this Memo

   This Internet-Draft is submitted in full conformance with the
   provisions of BCP 78 and BCP 79.

Internet-Draft               SCTP over DLTS                   March 2012

1.  Introduction

1.1.  Overview

   The Stream Control Transmission Protocol (SCTP) as defined in
   [RFC4960] is a transport protocol running on top of the network
   protocols IPv4 or IPv6.  This memo document specifies how SCTP can be
   used on top of the Datagram Transport Layer Security (DTLS) protocol.
   SCTP over DTLS is used by the RTCWeb protocol suite (see
   [I-D.ietf-rtcweb-overview] for an overview) for transporting non-
   media data between browsers.  The architecture of this stack is
   described in [I-D.jesup-rtcweb-data].

1.2.  Terminology

   This document uses the following terms:

   Association:  An SCTP association.

   Stream:  A unidirectional stream of an SCTP association.  It is
      uniquely identified by a stream identifier.

1.3.  Abbreviations

   DTLS:  Datagram Transport Layer Security.

   MTU:  Maximum Transmission Unit.

   PPID:  Payload Protocol Identifier.

   SCTP:  Stream Control Transmission Protocol.

   TCP:  Transmission Control Protocol.

   TLS:  Transport Layer Security.
