摘　　要：针对现有服务器集群的负载平衡算法不足,提出一种应用层自适应动态负载平衡算法。利用应用层特点,在负载均衡服务器端收集应用服务器负载信息,提出一种综合的权重计算方法,动态区分不同状态的服务器。通过自适应选择算法,合理分配请求至应用服务器。实验结果表明,在不同的负载情况下,该算法能有效地平衡负载,充分利用服务器资源。To overcome the shortage of load balancing algorithms of existing server cluster, we propose an application-layer adaptive dynamic （ALAD） load balancing algorithm. Based on the characteristics of the application layer, the load information of application servers is collected at load balancing server end. We present an integrated algorithm to calculate the weights. It differentiates the servers in different status dynamically; by adaptively selecting the algorithm, the requests can be distributed to application servers reasonably. Experimental result shows that under different load levels, the ALAD algorithm can effectively balance the load and brings the server resources into fullplay.
