给出了一种基于最优路径的适用于分布式视频点播服务器系统的请求迁移算法,本算法以提高系统的用户请求接受率和降低带宽消耗为目标,在随机早期迁移算法基础上,根据系统负载均衡度和带宽消耗,动态地选择最优迁移路径。实验结果证明,与随机早期迁移算法相比,这种算法增强了系统各服务器间的负载均衡,在提高了请求接受率的同时降低了带宽消耗,从而提高了系统的总体性能。 This paper presents a request migration algorithm based on the optimal path for distributed video on demand server system. This algorithm aims at improving the user acceptance rate and reducing the bandwidth consumption. Based on the random early migration algorithm, Load balancing and bandwidth consumption, dynamically select the optimal migration path. Experimental results show that, compared with the random early migration algorithm, this algorithm enhances the load balancing among the servers in the system, improves the system’s overall performance while improving the request acceptance rate and reducing the bandwidth consumption.
