摘　　要：目前使用单台网络计算机应用服务器难以满足大量用户的并发访问需求,在网络计算机系统中引入集群/负载均衡技术是解决这一问题的理想途径。研究网络计算机集群的负载均衡机制。设计和实现了适合于网络计算机应用模式的负载评估方法及负载状态更新机制,并在此基础上提出和实现了一种基于分布式协商的动态负载均衡算法。Currently, it is difficult for a single application server of network computer to provide remote application service for a large number of users accessing concurrently. It is necessary to design cluster system of network computer to deal with this problem. The mechnism of load balancing suit for the use of network computer is one of the key technologies for such system. The mechnism of load balance of network computer is researched. The mechnism of load evaluation and state update suit for network computer are designed and implemented. A dynamic load balancing algrithms based on distributed coordination are presented and implemented.
