摘要

传统的复制协议往往对如何适应遗留系统和引入复制技术对系统性能造成的影响方面考虑不够深入.本文在分析传统复制协议的基础上

提出了一种新协议.其设计采用复制实例数目可动态伸缩的逻辑令牌环结构

因而在满足可用性需求的前提下

可支持不同分布系统对适应性的需求

同时保证引入复制技术后系统的性能.文中详细论述了相应的系统模型和服务请求的处理

并通过与几种典型的传统复制协议的比较

证明了该协议的可行性.

Abstract

Traditional replication protocols don't take those issues into consideration such as adaptation to legacy system as well as affection to the system performance after introducing replication. Based on discussion about these protocols

a new replication protocol is addressed in this paper. Its design adopts logical token ring architecture with dynamically increasing/decreasing replicas. This paper discusses the system model and the request processing procedure of the protocol. With precondition to meet availability requirement

it not only enables adaptability to various distributed systems but also guarantees high performance of these systems. The comparison between this protocol and other typical replication protocols shows that it is feasible.
