                     Automatic Multicast Tunneling
                  draft-ietf-mboned-auto-multicast-17

Abstract

   This document describes Automatic Multicast Tunneling (AMT), a
   protocol for delivering multicast traffic from sources in a
   multicast-enabled network to receivers that lack multicast
   connectivity to the source network.  The protocol uses UDP
   encapsulation and unicast replication to provide this functionality.

   The AMT protocol is specifically designed to support rapid deployment
   by requiring minimal changes to existing network infrastructure.
