“An Analysis of the Flow-Based Fast Handover Method for

● Number of wireless terminals and applications increases ● Quality-of-Service sensitive applications and users ● Mobile IPv6 (MIPv6) standardized by the IETF to mobility management in IPv6 networks [1] ● Mobility made transparent to the application layer (L7) ● MIPv6 (L3) handover delay consists of ● Movement detection (RSOL, RADS, NUD) ● Care-of-Address configuration (Stateless or stateful address autoconfiguration, DAD) ● Address registration (BU-process to HA and CNs) Motivation 2/2 ● MIPv6 is a major improvement for mobility (vs. MIPv4): – No need for foreign agents, route optimization, stateless address autoconfiguration, in-built IPSEC etc. ● But MIPv6 doesn't solve the handover delay in IPv6 networks! – Handover delay occurs when MN moves to a new subnet (MIPv6 procedures take too much time) – Delay might cause packet loss! ● Handover delay is not acceptable with real-time applications (VoIP, conferencing, etc.) and affects also TCP-based applications (data transfer) MIPv6 optimizations ● Several proposals for the handover delay minimization
