Abstract
This paper describes an implementation and simulation of Zilog's ZNET, a Z80A microcomputer based local network. The network consists of a number os Zilog MCZ-2 microcomputer systems which communicate and share disk storage, line printers, and other devices using a passive coaxial cable. Each MCZ-2 node can support multiple processes and message transmission between processes within one node, across nodes, and between processes and shared devices. The OASIS Software Prototyping System is used to model network hardware and implement the operating system kernal which supports this message transmission facility. OASIS has been designed for developing prototypes of distributed software and simulating the execution of these software prototypes on modelled hardware. The objective of this paper is to illustrate the implementation of ZNET software using OASIS. The OASIS implementation provides both a specification of network software and a prototype which can be simulated to verify design adequacy and predict network performance.
