The Analysis of Performance for Priority Distinction Double-queue and Double-server Communication Network

In the field of modern communications network, the quality of a system performance usually determines the application of the system. This paper mainly uses the Markov chain theory to analysis the user blocking rate and losing rate, which are two important indicators of the priority distinction double-queue and double-server communication network(PDDDCN). Through mathematical analysis, we get the corresponding mathematical expression, and make the computer simulations. Simulation results show the correctness of the theoretical analysis, and the relationship between system performance and the arrival rate or the probability that ordinary users fail to relinquish a server.
