摘要
负载均衡一直是分布式网络的一个研究重点.近年来随着网络视频监控系统的广泛应用,负载均衡也逐步应用到该领域,以满足分布式视频监控的需要.本文针对分布式系统的视频服务器集群提出了一种新的负载均衡方案,将动态反馈机制与一致性哈希算法相结合,并根据其业务特性进行了优化和改进,增加了系统的可靠性和抗冲击性,提高了负载均衡的总体效果.
Load balancing is an important research field in distributed network.With the development of video surveillance system it is gradually applied in this field to meet the needs of distributed video monitoring in recent years.So a consistent hash load balancing algorithm based on dynamic feedback（CHDF） is proposed.It makes an optimization according to distributed video characteristics and increases the shock resistance and reliability.Simulation results show the effectiveness of algorithm.
