  1. Multicast Routing Optimization Juan-Carlos Zúñiga Luis M. Contreras Carlos J. Bernardos Seil Jeon Younghan Kim MULTIMOB WG, July 2012

  2. Multimob Routing Optimization (1/5) • http://datatracker.ietf.org/doc/draft-ietf-multimob-pmipv6-ropt/ • Solution provides optimal access to content located either in the local (Visited) or in the remote (Home or third party) network • The MAG has the logic/rules to decide whether a multicast subscription should be made in the local network or to the remote (e.g. Home) PMIPv6 domain • Decisions can be based on subscription model, which could be pre-configured or dynamically configured by operator (e.g. draft-gundavelli-netext-pmipv6-sipto-option) • MTMA serves as mobility anchor for remote subscriptions • Typically, the MTMA will be used to get access to multicast content from Home or any third party network

  3. Multimob Routing Optimization (2/5) • Remaining issues • [1] Document structure • [2] IPv4 support • [3] Expand details about dynamic decision to forward multicast traffic to local or remote • Suggested next steps at IETF83 • Organize the document by node operation instead of by function • Provide more details about the solution to dynamically decide on local or remote access

  4. Multimob Routing Optimization (3/5) • [1] Document structure • Intro (1) • Terminology (2) • Overview (3.1, 4.1, 6.1) • MAG operation (3.3, 4.3, 5.1, 5.2, 6.2, 6.3) • LMA operation (6.2) • MTMA operation (3.4, 6.2) • MN operation (3.2, 4.2, Considerations from RFC5213) • Data structures (5.3, Multicast group descriptor)

  5. Multimob Routing Optimization (4/5) • [2] IPv4 Support • Add details in accordance with RFC5213

  6. Multimob Routing Optimization (5/5) • [3] Provide more details about the solution to dynamically decide on local or remote access • For the dynamic policies, re-use PMIP signaling adding an option to carry a multicast group descriptor in the PBA message, similar to draft-gundavelli-netext-pmipv6-sipto-option • Use Multicast Address Record definition in RFC3810 as group descriptor, with some priority or mapping to home/visited (i.e. direct routing/MTMA)
