摘　　要：研究提高网络性能的问题,为了解决现有CDN网络中的负载平衡技术中用户的请求不能立刻得到响应的问题,提出了一种分布式装箱策略的负载平衡算法,算法可以充分利用网络拓扑信息和文件访问历史以及服务器的负载信息,构建一个完善、全面的中间层,并利用缓存、复制、负载平衡和DNS重定向等技术,实现对网络流量和各节点的负载实时处理。通过改进技术的仿真实验证明,分布式装箱策略完成了网络用户的请求导向最近的服务节点靠近,使得用户所需要的内容及时的分发,并可以缓解网络堵塞问题,提高用户访问网站的响应速度。The improvement of network performance is studied. In order to solve the problem that user＇s request can not responded immediately with existing CDN network technology, of load balance, the author proposed Load balance algorithm based on distributed strategy. First, the algorithm can be applied to network topology information and files access history and server load information to build perfect and overall middleware. Second, the algorithm can be applied to the technology of cache, copy and DNS load balance to realize real time processing of network layout and load of every node. The simulation of the technology proves that distributed strategy makes the request of network user route to the closest server node, so that the request can be sent immediately. The strategy carl ease network blocking as well and then improve the response speed to the terminal user.
