摘要
由于单个服务器的分布计算环境在实用性和系统性能方面存在着明显的缺陷,所以通过高速网络连接的多服务器系统提供冗余服务已成为当今分布计算技术的研究热点。本文介绍了一种基于主动工作模式分布式数据库服务器的构成及运行模型,为其建立了排队模型,并与非主动模式的系统进行了比较,以性能价格比优略为依据对其冗余度进行了数学解析。
There are obvious defects in the practicality and system performance of the distributed computing environments of a single server, so it has become a hot topic in the current distributed computing research to offer redundant servers by using a multi-server system connected by high-speed network. This paper introduces the structure and execution model of a kind of distributed database server based on the active work mode, constructs its queue model, compares it with non-active systems, and makes the mathematical analysis oF its redundancy on the basis of the performance/cost ratio.
