  2. HA1(LMA) HA1(LMA1) HA2(LMA2) CN PMIP Network PMIP Network AR(MAG1) AR(MAG1) AR(MAG2) MN MN CN Scenario 2 CN behind MAG Scenario 1 MIP6 enabled CN Problem Statement • PMIPv6 uses indirect routing via HA • Type 1 CNs • MIPv6 corresponding node functionality enabled, not behind PMIPv6 ‘MAG’ • Type 2 CNs • MNs behind PMIPv6 ‘MAG’ • Our solution for Type 1 CNs is adopted from enhanced RO draft(draft-ietf-mipshop-cga-cba)

  3. E-RO • Initial home address test • Early BU/BA exchange (care-of test) • Complete BU/BA • CGA for MN’s HoA based on RFC 3972 • CBA adopted with no change

  4. PMIPv6 RO (1/2) • Initial home address test -> Proxy Home Test • Early BU/BA exchange (care-of test) -> Early Proxy BU/BA • Added handover keygen token Home Agent (HA) MAG CN Proxy Home address Test Init (Proxy HoTI) Proxy HoTI Proxy Home address Test (Proxy HoT) Proxy HoT Early Proxy Binding Update (care-of test) Proxy Binding Acknowledge

  5. PMIPv6 RO (2/2) MN CN MAG2 MAG1 Handover context (Handover keygen token) Handoff Early Proxy Binding Update Proxy Binding Acknowledge Complete Proxy Binding Update Proxy Binding Acknowledge

  6. RO with CNs behind MAG(1/2) • MAG1 of MN needs to know CoA of CN which is provided by HA of CN • Proxy BU exchange between MAGs MAG2 (CN) Home Agent (CN) MAG1 (MN) Binding cache Request/Ack (CoA list of CNs) Proxy Binding Update Proxy Binding Acknowledgement

  7. RO with CN behind MAG(2/2) • RO in Handover MN MAG2 (MN) MAG1 MAG3 (CN) Context Transfer Request Context Transfer Data (CoA list of CNs) Proxy Binding Update Proxy Binding Acknowledgement

  8. Next Steps • Get more comments and revise accordingly • Issue a revised draft by next IETF • Listen to WG on the next steps
