  2. Protocol Extensions • Multicast traffic aggregation • Set up bi-directional GRE tunnel (M-Tunnel) between LMA and MAG • M-tunnels are dedicated to multicast data and message transmission between LMA and MAG and shared by all MNs at the MAG • Mobility support (i.e. seamless handover) • Scenario 1: With Policy Profile • When MN’s subscribing channel list is always maintained • Scenario 2: With multicast extended PBU/PBA • Use DeReg PBU and PBA having multicast channel information (PBU-M/PBA-M) • Scenario 3: With other fast handover mechanism, e.g., multicast extended CXTP • draft-vonhugo-multimob-cxtp-extension-00 81st IETF, July 2011

  3. Background • Both LMA and MAG act as PIM-SM routers • Support both ASM and SSM • Incoming IF on LMA/MAG is selected by an RPF lookup algorithm given by PIM • No tunnel convergence problem • Support local routing • Friendly with source mobility • No multicast protocol changes 81st IETF, July 2011

  4. Changes from -05 • Simplify the scenario • No use case for MLD proxy • Split CXTP extension into Dirk’s draft • Instead, DeReg PBU is extended to notify subscribing multicast channel information • Adopt GRE for M-Tunnel • Distinguish unicast transmission over IPv6-IPv6 LMA-MAG tunnel (according to Sri’s comment) • GRE key is negotiated with RFC5845 or statically • Editorial changes 81st IETF, July 2011

  5. Multicast Packet Format in M-tunnel IPv6 header (src= LMAA, dst= Proxy-CoA) /* Outer Header */ GRE header /* Encapsulation Header */ IPv6 header (src= S, dst= G) /* Inner Header */ Upper layer protocols /* Packet Content */

  6. Conclusion • This draft provides the extension for PMIPv6 with PIM-SM • The way to move forward • Go ahead with this story? • Split into two drafts? • “PMIPv6 multicast support with PIM-SM and M-Tunnel” • Intended status: Informational or BCP or Proposed Standard • “(P)BU/(P)BA extension for multicast handover” • Intended status: Proposed Standard 81st IETF, July 2011 6
