Efficient dynamic home agent discovery algorithm and system

摘要

An efficient and improved dynamic home agent discovery algorithm and system to be used in a protocol for network communications. The present invention encapsulates and integrates communications of the home agents into a single home agent communication. Communication between a mobile node and the home agents is simplified to a single home agent communication. Dynamic home agent discovery processes are performed, based on the single home agent communication. Encapsulation is achieved by having each of the home agents maintain a home agent list that contains information about each of the home agents coupled to the home link. A designated home agent receives and processes home agent discovery requests from the mobile node on behalf of home agents coupled to the home link, and a designated home agent sends home agent advertisements to and communicates with the mobile node.
