Abstract: An IP (Internet Protocol) session for a mobile node is carried out through the use of a virtual care-of address. A foreign agent sends an agent advertisement to the mobile node to allow the mobile node to choose from a list of IP addresses of the foreign agent. The foreign agent ties a virtual care-of address to a mobile node so that an intelligent and dynamic selection of tunnels to be used for the IP session can occur. Therefore, traffic for an IP session is not limited to transmission over the single particular tunnel that corresponds to an IP address initially selected by the mobile node. Rather, the virtual care-of address shifts the tunneling decision from the mobile node to the foreign agent. Supporting multiple tunnels between home agent and foreign agent allows resilience, redundancy, and service-level differentiation to mobile node traffic without involving the mobile node in the process.
