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.
Automatic Multicast Tunneling (AMT) is a protocol that uses UDP-based
encapsulation to overcome the aforementioned lack of multicast
connectivity. AMT enables sites, hosts or applications that do not
have native multicast access to a network with multicast connectivity
to a source, to request and receive SSM [RFC4607] and ASM [RFC1112]
traffic from a network that does provide multicast connectivity to
Working Group Summary
This document has received strong support from the working group and no
major controversies existed prior to the arriving at the IESG with
Subsequent to the previous IESG review, efforts have been made to address IESG
discuss issues, deal with IANA concerns and spin up new work associated with
congestion guidance for multicast applications.
A number of AMT implementations exist today and significant deployment
experience has been documented. This document has received thorough
review from the working group, and many have contributed to this effort
over the last 11+ years. In particular, Dave Thaler, Tom Pusateri,
Thomas Morin and Greg Bumgardner deserve credit for most of the
authorship of this document, and Bob Sayko, Doug Nortz and their
colleagues at ATT deserve credit for extremely thorough review of the
