FMIPv6 Usage with DNA Protocol draft-koodli-dna-fmip-00 Rajeev Koodli, Syam Madanapalli DNA WG, 63 IETF - Paris

Purpose of the draft To document how FMIPv6 can be used with DNA Informational

FMIPv6 & DNA FMIPv6 makes use of neighborhood information to expedite handovers DNA can provide fast detection of movement across subnets Scenarios where neighborhood information is unavailable, DNA can assist FMIPv6 for Reactive Handovers

Protocol Operation … 1.MN (re)associates with an Access Point and obtains the AP-ID 2.The MN searches for the [AP-ID, AR info] Tuple If [AP-ID AR info] is available, MN proceeds with FMIPv6 protocol If the tuple info is not available, MN invokes the DNA protocol 3.The MN sends a Router Solicitation with DNA extension (if any) 4.The MN receives a DNA Router Advertisement determines change in subnet configures new care of address and makes the address optimistic

Protocol Operation 5. MN sends a Fast Binding Update to PAR directly (i.e., without encapsulating inside FNA) 6. PAR should send a Handover Initiate message to the New Access Router 7. NAR should send a Handover Acknowledge message to the PAR 8. PAR sends a Fast Binding Acknowledgement message to the MN on the new link 9. PAR starts tunneling the packets to the MN's new CoA
