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共享和容错的方法。负载共享是指将工作从网络中负载较重的节点转移到负载较轻的节点，从而更好地为系统用户提供服务。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上放置作业的副本，这样，如果一个站点出现故障，则可以执行其作业的其中一个副本。本项目将研究在可能发生故障的网络中负载共享方案的性能，以及负载共享和容错方法的组合性能。

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.
