Abstract	Proxy Mobile IPv6 provides IP mobility to a mobile node by the proxy mobility agent called a Local Mobility Anchor and a Mobile Access Gateway without requiring mobile node臓�s participation in any mobility-related signaling. Increased demand for content-rich mobile data communications is prompting mobile network operators to deploy efficient mobility management including Proxy Mobile IPv6. The route optimization technique is applied to the data path between mobile nodes in the same Proxy Mobile IPv6 domain by bypassing the Local Mobility Anchor(s). However, when switching the data path from the default (non-optimized) route to an optimized one, the delay gap between these paths leads to performance degradation due to out-of-sequence packets, or unnecessary communication disruption. We propose a right-time path switching method for Proxy Mobile IPv6 route optimization. This method enables the Mobile Access Gateway to switch these paths with the accurate timing provided by the designated signaling messages, which prevents out-of-sequence packets as well as minimizing communication disruption during the route optimization procedure. The proposed method is evaluated in an actual testbed to show that the proposed method achieves the seamless path switch.
