  1. Multicast Routing Optimization Juan-Carlos Zúñiga Luis M. Contreras Carlos J. Bernardos Seil Jeon Younghan Kim MULTIMOB WG, November 2012 IETF 85, Atlanta

  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) • Addressed issues • Cleaned document structure • Added text for IPv4 support • Expanded details about dynamic decision to select multicast traffic from local or remote

  4. Multimob Routing Optimization (3/5) • Document structure in accordance with RFC5213 • Intro • Terminology • Overview • MAG operation • LMA operation • MTMA operation • MN operation • IPv4 support

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

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

  7. Next Steps • Reviewers? • Multiple Proxy upstreams?
