摘　　要：随着民航旅客服务信息系统规模的不断扩大和业务量的增加,导致服务器承载的信息量和访问量快速增长,如何有效地利用服务器资源处理海量的访问请求成为一个重要的问题,而有效的负载均衡策略是将用户的服务请求合理分配给这些服务器资源的关键。针对民航旅客服务信息系统中不同的服务请求对I/O、CPU和网络带宽等服务器资源请求消耗的不同,提出了一种改进的动态负载均衡算法。在民航旅客服务信息系统服务器中引入改进的动态负载均衡算法,并进行了实验对比验证,实验结果表明:该算法在增加服务器集群系统的吞吐量方面有着显著效果,并在现实应用中有较大的价值。With the continuous expansion of civil aviation passenger information service system and the buciness increase, the amount of information and traffic server load are growing rapidly. How to use the server resource to deal with a flood of access requests effectively becomes an important issue, and effective load balancing strategy is the key to the rational allocation of passengers＇ service requests to the server resources. Since different service requests have different server resources consumption to the I/O, CPU and network bandwidth in the civil aviation passenger information service system, an improved dynamic load balancing algorithm is proposed. The introduction of improved dynamic load balancing algorithm in civil aviation passenger information service system server has a significant effect in throughput increase of the server cluster system, and has great value in practical application.
