Reliability Optimization in Multiloop Communication Networks

Abstract

The rapidly growing interest in loop communication systems is accompanied by an increasing need to improve their reliability and reduce their vulnerability. This paper analyzes the reliability of multistage loop networks. Analytical expressions for topologies exhibiting maximum availability are obtained in terms of key-component down-time ratios. These optimal topologies are expressed in terms of terminal connections per subloop and subloops per higher level loops. The availability performance of these optimal topologies is investi-gated. Finally, the availability improvement obtainable by going to higher stage loop networks is investigated. Copyright © 1973 by The Institute of Electrical and Electronics Engineers, Inc.
