Future information networks require two modes of operations: datagram (connectionless) and virtual circuit (connection-oriented). The two major examples for each are IP(Internet) and ATM. Connectionless IP is far more efficient than virtual-circuit for browsing, email, and other non real-time services, but limited in capacity by its router-based architecture. Fixed-path ATM is suitable for services that demand quality guarantee and real-time delivery, but inefficient for many non-real time services due to its path-setup requirement.
Given the frenzied
popularity of Internet and the unshakable status of ATM as the broadband
standard, this research project will address two major research challenges:
(1) How do we efficiently integrate the two into a single network? and
(2) how do we break the throughput limit of the current Internet's router-based
architecture? We propose a new ATM/IP integrated network architecture.
The proposed network, called A/I Net, does not merely integrate the two.
It intends, through integration, to eliminate most of the inherent problems
of a stand-alone ATM or IP.
