摘　　要：慕课教育平台的服务器集群会在用户访问量的增加下响应变慢,所以需要提出一种基于服务器状态和请求信息新的策略算法来减少响应时间。该算法的机制是根据客户端的请求内容对服务器的影响程度进行分类,并设定相应的权值,同时结合服务器的性能参数和负载状态,将该次请求分配到负载最轻的服务器。根据慕课教育系统提出了一种分层式均衡系统的总体框架结构,研究了系统内部通信机制和Web服务器性能的监控方案。实验结果表明所提出的算法能够充分利用现有的软硬件资源,有效地均衡Web集群服务器的负载,使服务资源得到最大效率的利用,是目前缓解或者解决Web服务器负载不断增加的一种有效方法,优于一些传统的负载均衡算法。The server clustering of Mooc education platform will respond slower when the user traffic is increasing, so it needs to make a new strategy algorithm based on server state and request information to reduce the response time. Mechanism of the algorithm classifies the client＇s request according to its degree of influence on the servers, and sets the appropriate weight, combines the performance parameters with the load status of the servers, and assigns this request to the server with the lightest load. According to Mooc education system, it presents a hierarchical struc^xe of the overall framework of a balanced system, and studies the internal communication mechanism of system and web server performance monitoring program. Experimental results show that the proposed algorithm can make full use of existing hardware and software resources, and effectively balance the load of web cluster servers to enable service to maximize efficient use of resources. It is an effective method for the current alleviation and solution of increasing Web server load, and is better than some of the traditional load balancing algorithm.
