Performance Evaluation of Reliability Improvement Techniques for Single-Loop Communications Systems

Abstract

One of the basic terminal-attachment configurations is the loop. As such, it is receiving substantial attention. But it has been pointed out that loop communication networks are relatively vulnerable and unreliable. This paper considers the single-loop reliability problem. Three loop reliability (availability) improvement techniques are investigated in detail. All three techniques are based on using an auxilliary transmission path parallel to the main loop. A comparative study shows the best techniques. © 1974 IEEE
