Towards a Programmable Mobile IP

Abstract

Translate Article

This paper describes the design and implementation of a highly configurable and robust Mobile IP framework that employs active networking principles. Through the provision of open programmable interfaces and execution environment, new mobile services or application-specific customized services can be rapidly developed and deployed within the Mobile IP networking environment. ANTS [11] is being employed as the baseline active network execution environment for the implementation of our programmable Mobile IP framework. In particular, we have extended ANTS considerably to export mobile IP native interfaces to support mobile specific functionalities. The design of our active Mobile IP framework is currently implemented over the Linux operating system. The programmable framework is applied to the Mobile IP agent nodes namely, the mobile node, foreign agent, home agent and correspondent node. To demonstrate the ease of designing and deploying new mobile services, this paper describes the setup of an experiment to implement an active route optimization service.
