Reliability analysis of repairable queue system in communication network

Abstract

The retrial queue model with non-preemptive priority is established in order to Analysis the influence of the breakdowns of the server on the queueing indexes of the communication network. For our M/G/1 retrial queueing model, supplementary variable method is a suitable one for solving Some main reliability and queueing indexes, such as failure frequency, the reliability function of the server and the mean queue number are obtained in the steady-state condition. Besides, we give numerical examples to illustrate the effect of two parameters on several queueing performance characteristics. The derived queue and reliability indices of server can be used to optimize the performance measures of the communication network and improve the efficiency of the system.
