  2. Status of the Draft • Initial presentation • Extends FMIPv6 / PFMIPv6 with joint multicast context transfer messaging • Previous works: • draft-suh-mipshop-fmcast-mip6-00 (FMIP, 2004) • draft-xia-mipshop-fmip-multicast-01 (FMIP, 2007) • draft-hui-multimob-fast-handover-00 (PFMIP, 2009)

  3. Main Contributions • Defines a coherent multicast membership transfer based on MLD/IGMP state records (easy handling) • Defines a common Multicast Mobility Header Option • Defines per group feedback in Multicast Acknowledgement Option • Accounts for MLD/IGMP interoperability • Seamlessly plugs into FMIPv6 and PFMIPv6 protocol semantics and behavior
