This paper presents a client-server computing model which is established on an Ethernet-based LANs running under Novelr Netware. Simple PCs serve as clients and a powerful PC based system which contains an i860 RISC processor and an i486 CICS processor serves as the server. Remote program execution facilities with certain parallel capabilities are provided over the environment. And the design will allow this simple model to be extended to a Multiple-Client-Multiple-Server model, that with the mechanism each workstation can take the role of either a server or a client, thus the benefits from the use of the distributed computing environment described above can be realised. © 1992 IEEE.
