The IESG has approved the following document: - 'Extensions to support efficient carrying of multicast traffic in Layer-2 Tunneling Protocol (L2TP) ' <draft-ietf-l2tpext-mcast-05.txt> as an Experimental RFC This document is the product of the Layer Two Tunneling Protocol Extensions Working Group. The IESG contact persons are Thomas Narten and Margaret Wasserman. Technical Summary The Layer Two Tunneling Protocol (L2TP) provides a standard method for tunneling PPP packets. When IP multicast is used, the forwarding of multicast data within L2TP sessions may impact the throughput of L2TP tunnels because the same traffic may be sent multiple times within the same L2TP tunnel, but in different sessions. This document describes an extension to L2TP, in order to have an efficient use of L2TP tunnels within the context of deploying multicast services whose data will have to be conveyed by such tunnels. Working Group Summary There was support for this in the WG. Protocol Quality This document has been reviewed for the IESG by Thomas Narten. _______________________________________________ IETF-Announce@ietf.org https://www1.ietf.org/mailman/listinfo/ietf-announce
