It is important for distributed computing environments that communication networks are transparent to applications. This allows applications to make the best use of computer resources. To realize network transparency, communication platforms which support distributed computing environments should have a system configuration like an extension of a workstation's internal bus. Such communication platforms require high-speed communication paths, ability to handle different transmission speeds, high reliability, and scalability. This paper proposes a broadband distributed data network which satisfies the above requirements, and provides a distributed computing environment. Our system uses basic nodes called ATM-HUBs and ATM-Gateways (ATM-GWs) as its central components. The nodes consist of cell switch modules which can be made up of building blocks, ATM interface modules, and other functional modules. The switch module is connected to functional modules through a unified interface. The ATM-HUB in particular has conventional LAN interface modules. Using the conventional LAN interface and ATM interface module in an ATM-HUB, a wide variety of terminals, including conventional LAN terminals and ATM terminals, can be accommodated, so offering flexibility of communication modes to users. Furthermore, the use of star wiring around the ATM-HUB and media access control (MAC) address routing gives a higher transfer rate comparable to the speed of a physical transmission line for communication between ATM terminals, or between conventional LAN terminals.
