There is an irreversible trend in communications towards the transporting of all information in the form of packets. The world is served by thousands of interconnected synchronous networks, both old-fashioned telephone networks and their successors, but these networks are not suited to the transport of packets. The packet traffic is actually supported by tens of thousands of asynchronous (packet switching) router networks that overlay and utilize the resources of the synchronous networks. These redundant router networks represent a serious impediment to the realization of the full potential of the Internet. Ironically, they are instead oftimes treated as the solution.

Distributed Queue Switch Architecture (DQSA), a remarkable switching technology developed by Professor Graham Campbell (Ret.) and his students at Illinois Institute of Technology, eliminates the need for these redundant router networks. DQSA enables synchronous circuits to each be efficiently shared by hundreds or even thousands of users transmitting Ethernet or IP packets. Carriers using DQSA could provide a superior level of service that commingles packet and fixed-bandwidth offerings using only their already installed synchronous infrastructure -- no routers.

The benefits of DQSA are available in all wireless, MAN, LAN and satellite environments.

A white paper presenting an overview of DQSA plus graphical illustrations of several potential applications of DQSA are available at this site. Technical papers, simulations, tutorials, etc., are available at www.iit.edu/~dqrap.
