"Unicast-Prefix-based IPv4 Multicast Addresses", Dave Thaler, 25-Feb-08. ( bytes)

This specification defines an extension to the multicast addressing architecture of the IP Version 4 protocol. The extension presented in this document allows for unicast-prefix-based assignment of multicast addresses. By delegating multicast addresses at the same time as unicast prefixes, network operators will be able to identify their multicast addresses without needing to run an inter-domain allocation protocol.

"Overview of the Internet Multicast Addressing Architecture", Pekka Savola, 19-Oct-06. ( bytes)

The lack of up-to-date documentation on IP multicast address allocation and assignment procedures has caused a great deal of confusion. To clarify the situation, this memo describes the allocation and assignment techniques and mechanisms currently (as of this writing) in use.

"AAA Framework for Multicasting", Hiroaki Satou, 25-Feb-08. ( bytes)

IP multicast-based services, such as TV broadcasting or videoconferencing raise the issue of making sure that potential customers are fully entitled to access the corresponding contents. There is indeed a need for service and content providers to identify (if not authenticate, especially within the context of enforcing electronic payment schemes) and to invoice such customers in a reliable and efficient manner. This memo describes the framework for specifying the Authorization, Authentication and Accounting (AAA) capabilities that could be activated within the context of the deployment and the operation of IP multicast-based services. This framework addresses the requirements presented in draft-ietf-mboned-maccnt-req-04.txt, "Requirements for Accounting, Authentication and Authorization in Well Managed IP Multicasting Services". The memo provides a basic AAA enabled model as well as an extended fully enabled model with resource and admission control coordination.

"Lightweight IGMPv3 and MLDv2 Protocols", Hui Liu, 20-Nov-07. ( bytes)

This document describes lightweight IGMPv3 and MLDv2 protocols (LW- IGMPv3 and LW-MLDv2), which simplify the standard (full) versions of IGMPv3 and MLDv2. The interoperability with the full versions and the previous versions of IGMP and MLD is also taken into account.

"Multicast Ping Protocol", Stig Venaas, 21-Feb-08. ( bytes)

The Multicast Ping Protocol specified in this document allows for checking whether an endpoint can receive multicast, both Source- Specific Multicast (SSM) and Any-Source Multicast (ASM). It can also be used to obtain additional multicast related information like multicast tree setup time etc. This protocol is based on an implementation of tools called ssmping and asmping.

"Mtrace Version 2: Traceroute Facility for IP Multicast", Hitoshi Asaeda, Tatsuya Jinmei, Bill Fenner, Stephen Casner, 12-Nov-07. ( bytes)

This document describes the IP multicast traceroute facility. Unlike unicast traceroute, multicast traceroute requires special implementations on the part of routers. This specification describes the required functionality in multicast routers, as well as how management applications can use the new router functionality.
