The MQN was solved by analyzinga general open MQN with limited clients. In addition, the steady-state probability distribution theorem was proven.Thus, analytical load indices such as queue length at the servers and the server efficiency were obtained. Moreover,the sufficient and necessary conditions for server load balance were found. Finally, a client/server system was analyzed to illustrate the procedure for computing system load indices. The results are not only helpful for analyzing bottlenecks in the client/server system, but are also fundamental to static system configuration design.展开更多
