摘要:
对于诸如Web服务这种面向广域环境的分布计算,服务应答慢等同于不可用。它在不改变可用性的前提下对算法的性能提出了很高的要求。然而目前的容错算法很少致力于提高算法的性能。文中提出一种新的复制算法RRR。它的主要优点是:应答由处理速度最快的副本返回,响应时间短;节约系统资源;基于主动复制,但避免了重复嵌套呼叫问题。最后用理论分析和实验证明了算法的优点
Abstract:
To the wide area network oriented distributed computing such as Web services, a slow service is equivalent to an unavailable service. It makes demands of effectively improving the performance without damaging availability to the replication algorithms. However, existing replication algorithms seldom address to improve the performance. Propose a new replication algorithm named RRR. Its main advantages are: Its response time is short because the response is returned by the fastest replica; It economizes the system resources; It is based on the active replication algorithm, but it avoids the redundant nested invocation problem. Finally prove the advantages by analyzing and experiments
