Softnet supports for extended mobile IP protocol

In order to solve the problems such as low performance, security limitation, and deployment-difficulty of new protocols in implementing the basic mobile IP protocol, an extended mobile IP protocol is implemented on an active network prototype-Softnet. The Softnet has the feature of dynamic loading of the mobile agents that dynamically extends functions of the active node. Routing tables for the extended mobile protocol are maintained using a re-directional active network encapsulation protocol. The performance of the mobile IP is improved and the limitation caused by security consideration is also eliminated by integrating mobile-IP routing, normal node routing and tunneling techniques.
