Automatic Multicast Tunneling
RFC 7450, “Automatic Multicast Tunneling”, is a Proposed Standard document published in February 2015 by G. Bumgardner. It has since been updated by RFC 8777, RFC 9601. The canonical text is published by the RFC Editor.
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.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
