A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Inter-Domain Multicast Routing Working Group of the IETF. Title : Internet Group Management Protocol, Version 3 Author(s) : B. Cain, S. Deering, A. Thyagarajan Filename : draft-ietf-idmr-igmp-v3-01.txt Pages : 33 Date : 19-Feb-99 This document specifies Version 3 of the Internet Group Management Protocol, IGMPv3. IGMP is the protocol used by IP systems to report their IP multicast group memberships to neighboring multicast routers. Version 3 of IGMP adds support for ''source filtering'', that is, the ability for a system to report interest in receiving packets *only* from specific source addresses, or from *all but* specific source addresses, sent to a particular multicast address. That information may be used by multicast routing protocols to avoid delivering multicast packets from specific sources to networks where there are no interested receivers. This document is a product of the Inter-Domain Multicast Routing working group within the Internet Engineering Task Force. Comments are solicited and should be addressed to the working group's mailing list at idmr@cs.ucl.ac.uk and/or the author(s).

A list of Internet-Drafts directories can be found in http://www.ietf.org/shadow.html or ftp://ftp.ietf.org/ietf/1shadow-sites.txt Internet-Drafts can also be obtained by e-mail. Send a message to: mailserv@ietf.org. In the body type: "FILE /internet-drafts/draft-ietf-idmr-igmp-v3-01.txt". NOTE: The mail server at ietf.org can return the document in MIME-encoded form by using the "mpack" utility. To use this feature, insert the command "ENCODING mime" before the "FILE" command. To decode the response(s), you will need "munpack" or a MIME-compliant mail reader. Different MIME-compliant mail readers exhibit different behavior, especially when dealing with "multipart" MIME messages (i.e. documents which have been split up into multiple messages), so check your local documentation on how to manipulate these messages. Below is the data which will enable a MIME compliant mail reader implementation to automatically retrieve the ASCII version of the Internet-Draft.
