RUI-Performance Analysis of Load Sharing and Fault Tolerance Methods in Distributed Computing Systems

这个项目的主要目标是研究在分布式计算系统中实现负载分担和容错的方法。负载共享方法涉及将作业从网络中负载较重的节点转移到负载较轻的节点，以向系统用户提供更好的服务。提出并分析了几种负荷分担方案。容错方法包括在网络中的多个站点放置作业副本，以便在一个站点发生故障时，可以执行其中一个作业副本。本项目将研究负载分担方案在可能发生故障的网络中的性能，以及负载分担和容错组合方法的性能。

The principal goal of this project is to investigate methods for implementing both load sharing and fault tolerance in distributed computing systems. Load sharing methods involve transferring jobs from heavily loaded nodes in the network to more lightly loaded nodes to give better service to the users of the system. Several schemes for load sharing have been proposed and analyzed. Fault tolerance methods involve placing copies of jobs at multiple sites in the network, so that if a site fails, one of the copies of its jobs can be executed. This project will investigate the performance of load sharing schemes in networks in which failures may occur, and the performance of combined load sharing and fault tolerance methods.
