This draft is a work item of the Inter-Domain Multicast Routing Working Group of the IETF. Title : Socket Interface Extensions for Multicast Source Filters Author(s) : D. Thaler, B. Fenner, B. Quinn Filename : draft-ietf-idmr-msf-api-03.txt Pages : 14 Date : 03-Jul-02 IGMPv3 for IPv4 adds the capability for applications to express source filters on multicast group memberships, which allows receiver applications to determine the set of senders (sources) from which to accept multicast traffic. This capability also simplifies support of one-to-many type multicast applications. It is expected that in the future, the same capability will be available in IPv6 as well. This document specifies new socket options and ioctl commands to manage source filters for IP Multicast group memberships. It also defines the socket structures to provide input and output arguments to these new APIs. These extensions are designed to provide access to the source filtering features, while introducing a minimum of change into the system and providing complete compatibility for existing multicast applications. A URL for this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-idmr-msf-api-03.txt To remove yourself from the IETF Announcement list, send a message to ietf-announce-request with the word unsubscribe in the body of the message. Internet-Drafts are also available by anonymous FTP. Login with the username "anonymous" and a password of your e-mail address. After logging in, type "cd internet-drafts" and then "get draft-ietf-idmr-msf-api-03.txt". 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-msf-api-03.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. --NextPart Content-Type: Multipart/Alternative; Boundary="OtherAccess" --OtherAccess Content-Type: Message/External-body; access-type="mail-server"; server="mailserv@ietf.org" Content-Type: text/plain Content-ID: <20020703132049.I-D@ietf.org> ENCODING mime FILE /internet-drafts/draft-ietf-idmr-msf-api-03.txt --OtherAccess Content-Type: Message/External-body; name="draft-ietf-idmr-msf-api-03.txt"; site="ftp.ietf.org"; access-type="anon-ftp"; directory="internet-drafts" Content-Type: text/plain Content-ID: <20020703132049.I-D@ietf.org> --OtherAccess-- --NextPart-- From owner-idmr@cs.ucl.ac.uk Fri Jul 5 08:51:18 2002 Received: from pan2.cs.ucl.ac.uk (pan2.cs.ucl.ac.uk [128.16.8.208]) by ietf.org (8.9.1a/8.9.1a) with SMTP id IAA22484 for ; Fri, 5 Jul 2002 08:51:18 -0400 (EDT) Received: from pan2.cs.ucl.ac.uk by pan2.cs.ucl.ac.uk via Local Delivery channel id ; Fri, 5 Jul 2002 13:25:55 +0100 Received: from bells.cs.ucl.ac.uk by pan2.cs.ucl.ac.uk with local SMTP id ; Fri, 5 Jul 2002 12:53:43 +0100 Received: from odin.ietf.org by bells.cs.ucl.ac.uk with Internet SMTP id ; Fri, 5 Jul 2002 12:47:27 +0100 Received: from CNRI.Reston.VA.US (localhost [127.0.0.1]) by ietf.org (8.9.1a/8.9.1a) with ESMTP id HAA19900; Fri, 5 Jul 2002 07:46:35 -0400 (EDT) Message-Id: <200207051146.HAA19900@ietf.org> To: IETF-Announce:; Cc: RFC Editor Cc: Internet Architecture Board Cc: idmr@cs.ucl.ac.uk From: The IESG Subject: Protocol Action: Internet Group Management Protocol, Version 3 to Proposed Standard Date: Fri, 05 Jul 2002 07:46:34 -0400 Sender: owner-idmr@cs.ucl.ac.uk Precedence: bulk The IESG has approved the Internet-Draft 'Internet Group Management Protocol, Version 3' as a Proposed Standard.
