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. To perform virtual care-of address services, the foreign agent ties the 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.

Description

Technical field [0001] The embodiments of the present invention relate to the field of mobile IP (Internet Protocol); and more specifically, to virtual care-of addresses assigned to mobile nodes. Background technique [0002] Mobile IP is a protocol described in Request for Comments (RFC) 3344 in August 2002, which allows laptops or other mobile computing units (referred to as mobile nodes in this article) to various sub-networks at various locations Roam between while maintaining Internet and / or WAN connectivity. Mobile agents (e.g., home agents, foreign agents) provide mobile IP functionality. In a typical mobile IP network, each mobile node is identified by its home address (assigned by the home agent) regardless of its current point of attachment to the Internet. Although far away from its home, the mobile node is also associated with a care-of address (provided by a foreign agent), which indicates the mobile node's current point of attachment for reachability. Although th...
