  1. Fast Handover For Multicast in Proxy Mobile IPv6 Dapeng Liu/Min Hui/Hui Deng

  2. Motivation • The existing solution for PMIPv6 multicast specifies that, only after the bi-directional tunnel is built between n-MAG and LMA using the multicast packet can be continuously delivered to MN. • It inevitably causes the latency and loss of packet during handover process • Proposal: A fast handover mechanism to support multicast for PMIPv6

  3. PMIP multicast fast handover SolutionOverview LMA • P-MAG and N-MAG establishing • bi-directional tunnel to forward • multicast traffic • Extend HI (handover Initiate) message to carry multicast context information P-MAG n-MAG MN MN

  4. Handover Procedure LMA MN P-MAG n-MAG (1) HO Initiate (2) HI (MN ID, n-MAG ID) (MN ID, Multicast State) (3) HAck (4) HI/HAck (5) (6) Handover (7) Multicast Data (8) PBU-M (9) PBA (10)Multicast Data (11)HI/HAck

  5. Extension of HI message A new flag (M) is included in the HI Mobility Header message with multicast extension. The rest of the message format remains the same as defined in [3]. When (M) flag is specified in HI Mobility Header message, the mobility options field needs to be extended to include the multicast addresses.

  6. Discussion • What is the next step?
