  1. Seamless Handover for Multiple-Access Mobile Node in PMIPv6 draft-cui-netext-pmipv6-shpmipv6-00 Yong cui, XinXu, WD. Wang, XM. Li, YZ. Huo, W. Luo Atlanta, NetExt WG, 2012-11-5

  2. Motivation • RFC 5949 has proposed two modes of fast handover scheme, but both of them have a limit • Just use one interface to handle all packets, even when the interface is under handover • The size of packet buffer may be the bottleneck, and the storage-and-forward model may bring a transmission delay • It’s possible to use the multi-access features of the MN to solve the problem.

  3. Multi-access MN Handover scenario LMA router PMAG SMAG NMAG IF1 IF2 IF2 IF1 MN MN

  4. Solutions • Basic Idea • Use the available interface of the MN to handle the packet that transport on the interface under handover • Solutions • Build a bi-directional tunnel between MAGs that the MN is attaching to • When PMAG finds that the interface is under handover, it forwards packet to the SMAG • When LMAfinds that the interface has leaved from PMAG afterward , it change its encapsulating destination to the SMAG

  5. Handover signaling New interface registration MAGs intereact Handovering: MAG forward packets Handovering: LMA forward packets

  6. Message formats • Streamless Handover Initiate (SHI) Notice: this message Must include MN-ID option

  7. Message formats • Streamless Handover Acknowledge (SHAck)

  8. Next step • Any questions/comments?
