摘　　要：流媒体是视频监控系统的核心技术,文章以国网山西省电力公司生产视频监控系统对流媒体服务的需求为出发点,提出了基于动态加权最小连接数负载均衡算法的流媒体集群技术。与单一服务器相比,集群系统明显增强了服务的可行性与稳健性,与以往的负载均衡算法相比,结合流媒体服务特性的负载均衡算法兼顾了服务器状态、性能、连接数3个因素,能够更加合理地分配系统资源,并能有效解决超负载情况下服务响应慢的问题。Streaming media is the core technology of video monitoring system. For the purpose of adapting to the needs of streaming media services in Shanxi electric video monitoring system, this paper proposed a streaming media cluster system based on dynamic weighted minimum link load balancing algorithm. Compared to the single server system, the cluster system signifi cantly enhanced the feasibility and robustness of service. Compared with the conventional load balancing algorithms, load balancing algorithm with streaming media service characteristics considers the server status, performance and connection number. With these 3 factors, the algorithm can allocate system resources more rationally and solve the problem of server response slow under the ultra-load effectively.
