Throughput analysis of timed token protocols in double ring networks

A study of the throughput and time characteristics of double-ring networks is presented, assuming that the two channels are used for balancing the traffic (when both are working) and for synchronous traffic generated according to a generic but periodic pattern. In addition, reconfiguration using portions of both rings to circumvent faulty elements in a double ring network is shown to be equivalent to the single ring configuration already studied. Examples of applications of the results are also illustrated
