Abstract

The advantages and benefits provided by multicast technologies are well known. There are a number of application areas that are ideal candidates for the use of multicast, including media broadcasting, video conferencing, collaboration, real-time data feeds, data replication, and software updates. Unfortunately, many of these applications lack multicast connectivity to networks that carry traffic generated by multicast sources. The reasons for the lack of connectivity vary but are primarily the result of service provider policies and network limitations.

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.
