  1. Rapid acquisition of the MN multicast subscription after handover Luis M. Contreras, Carlos J. Bernardos Universidad Carlos III de Madrid (UC3M) Ignacio Soto Universidad Politécnica de Madrid (UPM) Quebec City, MULTIMOB WG, July 2011 1

  2. Proposal Status Initial draft version submitted for 78th IETF meeting in Maastricht Proposal included in re-chartering discussion during 78th IETF Draft firstly presented in Beijing 79th IETF meeting Updated version submitted for 81st IETF: draft-contreras-multimob-rams-01.txt Currently waiting for feedback from the list to progress 81st IETF, Quebec City 2

  3. Draft Motivation The draft covers the MULTIMOB charter goal of optimizing multicast traffic during a handover Main contribution: to accelerate the MAG’s knowledge acquisition of the MN’s multicast subscription (i.e., IP addresses of the multicast group subscribed by the MN, and the source providing it) Main advantages: MAG acquisition of MN’s multicast status is decoupled from: Underlaying radio technology: different delays for distinct technologies (framing, retransmissions, resource mgmt, etc) IGMP/MLD parametrization tuning: different delays due to MLD message processing capabilities by distinct MNs, different timers per IGMP/MLD distinct flavours (including those being defined in MULTIMOB) PMIPv6 multicast architecture (current or evolved): solution compatible with base solution and also with solutions being proposed for solving tunnel convergence issue 81st IETF, Quebec City 3

  4. Predictive handover 81st IETF, Quebec City 4

  5. Reactive handover 81st IETF, Quebec City 5
