Publication number: 20040029555Abstract: A system for supporting mobile Internet protocol (mobile IP) using multiple separate tunnels and a method therefor. Separate tunnels can be created between a mobile node and a correspondent node in a communication network compliant to mobile IP, when the mobile node and the correspondent node are communicating with each other. The separate tunnels each are across respective subnets and are used to deliver different packets according to respective packet routing policies. Therefore, the effective bandwidth between the mobile node and its home agent can be increased so as to increase the transmission rate for sending and receiving packets by the mobile node. The mobile node or the home agent routes packets via individual separate tunnels according to respective packet routing policies. The packet routing policies can be individually based on a ratio of respective status parameters of the separate tunnels or of respective costs of the separate tunnels, or on a user-defined manner.Type: ApplicationFiled: March 4, 2003Publication date: February 12, 2004Inventors: Hsien-Ming Tsai, Ming-Xian Jiang, Jammy Huang
