摘　　要：校园网格中的视频点播系统表现形式的直观性,自主性一直受到校园内师生的广泛关注,但视频服务器节点响应能力低下,视频点播中的缓冲和延迟而导致点播不能适应实时、连续稳定的视频流。通过分析视频点播系统面临的诸多问题,根据校园网格的特点和影响负载均衡的因素,对基于校园网格的负载均衡技术进行了分析,提出一种动态负载均衡算法,实现校园网络中视频资源的共享、均衡校园视频资源的负载。测试表明该算法可行、有效。The intuition and autonomy of the video- on- demand system under campus grid has been widely concerned by the teachers and students in the camps. But the low performance responding ability of serve and the delaying of the video- on - demand in the buffer make that the on - demand can not meet the real time, continuous video streaming. By analyzing many problems of the video - on - demand system faced with, according to the characters of the Campus Grid and the disturbed factors of load balancing, based on the analysis of the campus grid load balancing technology, this paper propose a dynamic loading balancing algorithm to realize the sharing of the video resource and balance the loading of the video resource under the camps network. The test shows that the algorithm is feasible and effective.
