The IESG has approved the Internet-Draft "Support for Multicast over UNI 3.0/3.1 based ATM Networks." <draft-ietf-ipatm-ipmc-12.txt> as a Proposed Standard. This document is the product of the IP Over Asynchronous Transfer Mode Working Group. The IESG contact persons are Frank Kastenholz and Jeffrey Burgan. Technical Summary This protocol provides multicast support over ATM networks for IP hosts. It operates by defining a multicast server. The multicast server operates in one of two modes. In the first mode it provides the ATM address of each node in a multicast group (in which case the node sending the multicast uses a point-to-multipoint VC to transmit a multicast datagram to all recipients). In the second mode, the server performs the actual multicast distribution; nodes send their multicast packets to the server, which then distributes the multicast packets to all members of the multicast group. In all cases, nodes wishing to receive packets for a specific multicast group must register with the multicast server. Working Group Summary This protocol is a product of the IP/ATM working group. There was no significant dissent in the working group. No comments were received during the IETF last call. Protocol Quality This protocol has been reviewed for the IESG by Frank Kastenholz and Jeffrey Burgan.
