A Network Architecture for Continuous Mobility

A system architecture for continuous mobility of Internetconnected computers is designed and proposed. The architecture considers network transparency, geographical location transparency, and performance transparency, with strong support for mapping between an identi er space of the Internet and geographical location information. The architecture is de ned by 1) identi er space support functions, 2) continuous Internet connectivity functions, and 3) performance transparency functions. Two experimental systems are implemented based on the architecture and are tested. The systems achieve continuous mobility in practical environments for automobiles connecting to the Internet, and in classrooms with about 40 roaming students.
