摘　　要：负载的均匀分布是大型电网视频监控系统中实现有效多级级联的关键问题,需要采用一种改进的负载均衡方法来应对该问题。该方法是先判断收到业务请求类型在流媒体服务器采集设备的被请求率达到门限值,然后选取在状态参数低于已设定阈值且与业务请求类型相匹配的流媒体服务器进行请求处理。实验证明该方法不仅避免了由于自身性能的不足而造成的高负载,而且保证了负载均衡的准确性和高效性。Uniformly distributed load is the key problem to the effectiveness of the multi-stage cascade large in the power grid video surveillance system.An improved load balancing method is needed to cope with this problem.First,this method is to judged the threshold of the requested rate about a kind of service request collected by streaming media server acquisition equipment is reached. Second,the streaming media server is selected based on the status parameters less than the set threshold and the type of service request matched to process the requests.The experiments show that this method not only avoids the high load due to lack of performance caused by itself,but also to ensure the accuracy and efficiency of the load balancing.
