he many advances in computer technology in recent years, one significant development has been the use of networks as a means of sharing resources among multiple computer systems. Despite the considerable successes achieved on this front, limitations have become apparent in the current generation of network-based resource sharing technology. The recent introduction of gigabit-per-second local area networking and high-performance storage device technologies now provide the basis for a new class of networked system. Our recent efforts have involved realizing a system which supports resource sharing among computer systems in a very high performance network- based environment. Developments range from integration of the HIPPI-based networked systems to new protocols for data transport to the incorporation of the UniTree system as the coordinating entity for system-wide storage and file management. This paper presents an overview of considerations for this style of network-based resource sharing.
