One of the obstacles to implementing AMT Multicast in a multi-network
environment is the difficulty an AMT Gateway may have in finding an
AMT Relay that is optimal. Optimal in this context means that the
AMT Relay has multicast connectivity to the Source, and its location
minimizes the unicast (tunneled) portion of the path to the Gateway.
Blind use of the global anycast address specified for AMT Relays in
"Automatic IP Multicast Without Explicit Tunnels (AMT)" could result
in reaching an AMT Relay that does not have multicast connectivity to
the source, which would yield a failure to obtain the multicast
content; or it could result in reaching an AMT Relay that is
otherwise less than optimal. This document proposes a method for
implementing standard DNS procedures so that an AMT Gateway using
normal DNS queries can virtually always find the optimal AMT Relay
for a given Source.
