我们考虑的最佳镜像分配问题的目的是在网络服务器的负载平衡。针对高可靠性网络的构建问题，考虑可靠性和成本之间的权衡关系，提出了在成本和时延约束下，使系统可靠性最大化的最优镜像分配模型.该优化模型能够处理各种网络拓扑结构。在这个模型中，我们将这个优化问题表示为一个0-1整数规划，我们可以找到每个镜像服务器应该在哪里，以及镜像服务器的具体文件分配。我们的目标是通过求解这个模型来找到最优的镜像分配，并定量地展示分布式镜像分配在负载平衡和提高系统可靠性方面的一般特性。
We consider the optimal mirror allocation problems for the purpose of load balance in network servers. We focus on constructing high-reliability networks, and propose the optimal mirror allocation model such that the system reliability is maximized subject to costs and delays, in view of the trading-off relationship between the reliability and cost. This optimization model is capable of dealing with various kinds of network topology. We formulate this optimization problem as a 0-1 integer programming in this model, and we can find the place where each mirror server should be and the concrete assignment of files to mirror servers. Our objective is to find the optimal mirror allocation by solving this model, and to show the general characteristics about the load balance and the improvement of the system reliability by the distributed mirror allocation, quantitatively.
