多类服务器计算机网络系统优化配置研究

Study on configuration optimization to multiservercomputer networks system

采用马尔可夫排队网络，建立了具有多类服务器并考虑网络影响的基于Ｃｌｉｅｎｔ／Ｓｅｒｖｅｒ平台的计算机网络系统的数学模型，给出了有限源开环马尔可夫排队网络的稳态分布概率的一般解．在此基础上，推出系统负载指标的解析结果，分析、论证系统服务器负载均衡的条件，提出归一化的性能指标向量，建立系统优化目标函数，研究不同情形下的配置优化求解方法．

A queuing network model based on Markov queuing network to multiserver computer networks system based on client/server architecture is presented.On the base of Cordon theorem,the solution of this model is emphatically studied,and analytic performance result to the model is presented.Computer program is compiled.An objective function for system configuration optimization and related algorithm under different situations are the obtained.An example is given for verification.
