Multicast Routing Optimization Techniques for PMIPv6 Networks

This draft presents a comprehensive solution for multicast routing optimization in PMIPv6 networks by combining two significant methodologies: Direct Routing and MTMA (M-LMA). It aims to address routing convergence challenges and incorporates insights from use cases discussed at a previous IETF meeting. The solution ensures optimal content access, whether located in local or remote networks. It empowers the Mobility Access Gateway (MAG) to determine the multicast subscription strategy based on subscription models that can be configured either statically or dynamically by the operator.

  1. Multicast Routing Optimization Juan-Carlos Zúñiga Seil Jeon Luis M. Contreras Carlos J. Bernardos Younghan Kim MULTIMOB WG, November 2011 82nd IETF, Taipei

  2. Multimob Routing Optimization (1/2) https://datatracker.ietf.org/doc/draft-zuniga-multimob-pmipv6-ropt/ • Combines the two drafts: Direct Routing and MTMA (M-LMA) providing a more complete solution to the routing convergence problem • Addresses the Use Cases presented by Thomas in Quebec • Solution provides optimal access to content located either in the Local or in the Remote network

  3. Multimob Routing Optimization (1/2) • MAG decides whether a multicast subscription should be made in the local network or to the remote (e.g. Home) PMIP domain • MAG can be an MLD Proxy or a Multicast Router • Decisions can be based on subscription model, which could be pre-configured or dynamically configured by operator (e.g. [I-D.gundavelli-netext-pmipv6-sipto-option]
