Abstract
This paper describes an implementation and simulation model
of Zilog's ZNET, a Z80A microcomputer based local network. The network consists of
a number of 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
messagetransmission between processes within one node, across nodes, and
between processes and shared devices. The OASIS Programming Language is
used to model network hardware and implement the operating system kernal
which supports this message transmission facility.
OASIS has been designed for the implementation of multicomputer system
software and the simulated execution of this software by modelled
system hardware. The objective of this paper is to illustrate the
implementation of ZNET software using OASIS. This OASIS implementation
provides both a specification of network software and a model which
can be simulated to predict network performance.
