Latest Patents

One of Yi-Wen Liu's latest patents is titled "Apparatus of dynamically assigning external home agent for mobile virtual private networks and method for the same." This invention proposes an apparatus that dynamically assigns an external home agent (HA) for VPNs. The apparatus establishes a VPN between an internal network and at least one external network, allowing a mobile node (MN) to roam securely in the external network. The external HA that is closest to the MN in the visited external network is selected for mobility management. This innovation ensures that the MN only needs to register with the same external HA when roaming within the same external network. As a result, the handoff latency and end-to-end latency for a roaming MN are significantly reduced. Additionally, it eliminates the need to reestablish the IPsec tunnel within the same external network.
