摘要
基于机群的可扩展计算机网络已逐渐成为高性能网络服务器架构的基础。文章对几种典型的机群构架进行了研究，包括RR-DNS + Web服务器 + AFS服务器、TCP路由器+Web服务器、主-从服务器等，对它们的并行性问题，例如可扩展性、可靠性以及负载平衡策略等，作了深入的比较分析。
Cluster-based systems have become the foundation of the architecture of high-performance Web servers. This paper gives a view of several typical approaches to manage physically independent nodes in cluster systems, including RR-DNS + Web server +AFS server, TCP router + Web server and master-slave architectures. The parallel aspects of different approaches, such as scalability, availability and load balance, are also discussed.
