A Distributed Computing Network for Real-Time Systems.

Abstract

Partial interconnection, ring, and global bus topologies are examined for use in a real-time distributed computing network. Message lengths and capacity allocation strategies for network links are evaluated in determining system performance based on average message delay. The data suggest a network topology for the application under study. Processor delays at each of the nine nodes in the network are introduced in a simulation model of a global bus network. Thus, link traffic and processor delays are used with message arrival rate, network bandwidth, and processor capacity parameters to arrive at a satisfactory computer system network for a real-time application. A method is developed whereby software requirements are determined in terms of the number of instructions executed. The desired system response time is established and software and hardware specifications may then be defined.
