Abstract
A computer protocol that manages and provides efficient communications and utilization of resources between a mobile computer system or device and other systems and devices. Each home agent maintains a home agent list containing information about each of the home agents coupled to the home link. A designated home agent on behalf of the home agents for a virtual home agent is used to send and broadcast home agent advertisement, to receive and process a request from a mobile node, to process and send a reply to the mobile node. Synchronization mechanisms or tools, such as home agent priority or floating token method, are provided for proper operation of a Virtual Distribution Home Agent Protocol (VDHAP). These mechanisms or tools are used to fairly distribute loads from the mobile node among the home agents within the virtual home agent.
