| 摘 要： | 在大型VOD(Video On Demand)系统中,服务器需要响应来自用户的大量并发请求,不仅视频服务器成为系统的瓶颈,负责负载均衡的应用服务器也日益成为系统的瓶颈.基于分布式VOD系统的结构,采用并行遗传算法对大型分布式VOD系统的负载均衡进行了研究,提出并实现了一种基于并行遗传算法的分布式VOD系统负载均衡调度算法.实验结果表明,与不采用负载均衡和采用串行遗传算法的负载均衡调度算法相比,该算法能够显著提高VOD系统的处理性能和响应能力. |

| Abstract: | In large-scale VOD system,the server needs to response to a great deal of concurrent requests,so not only the video server becomes the system's bottleneck,but the application server which takes charge for load balancing also growingly becomes the system's bottleneck.Based on the structure of distributed VOD system and combined with the characteristics of Parallel Genetic Algorithm,in this paper it explores the load balancing of large-scale distributed VOD system,proposes and implements a Parallel Genetic Al... |
