                       CLUE Protocol Data Channel
                   draft-holmberg-clue-datachannel-02

Abstract

   This document specifies how to use the Stream Control Transmission
   Protocol (SCTP) on top of the Datagram Transport Layer Security
   (DTLS) protocol (SCTPoDTLS) for transporting CLUE protocol messages
   between CLUE entities.

   The document describes the SCTP considerations for CLUE, and the SDP
   Offer/Answer procedures for negotiating a SCTPoDTLS connection for
   CLUE.

   Details and procedures associated with the CLUE protocol are outside
   the scope of this document.
