摘要
Proxy Mobile IPv6 (PMIPv6) is one of the most promising technologies for next generation IP network. Fast Handover for PMIPv6 (FPMIPv6) was standardized to improve the handover performance of PMIPv6. However, the long interruption of Lay 2/lay 3 handover in PMIPv6 and FPMIPv6 may be unacceptable for delay-sensitive real-time multimedia applications (e. g. VoIP). To decrease the handover latency, we propose a seamless handover scheme for multi-interface Mobile Node(MN). In this scheme, MN and network units are enhanced to send/forward the packets that destined to handover interface to some other interfaces belonging to MN, which make MN can continuously send/receive packets during handover process. Both theory analysis and Linux-based testbed evaluation have proven that our seamless handover scheme can greatly decrease handover latency and improve the performance of PMIPv6.
