摘　　要：为解决民航业大规模分布式集群系统中服务的亲和性和负载均衡问题,研究JCF中间件平台上原有的负载均衡算法以及常见的负载均衡方法,提出一种亲和性动态负载均衡算法。提取用户标识信息,使用哈希映射方式分配用户请求,将同一用户连续请求映射到相同的目标服务器,针对集群规模变化情况设计动态调整策略。实验结果表明,该算法能够有效解决服务的亲和性和负载均衡问题,保证集群系统的稳定性和可伸缩性。To deal with service affinity and load balancing in large-scale distributed cluster system of civil aviation industry,the original load balancing algorithm on JCF middleware platform and the common load balancing method were studied,and affinity dynamic load balancing algorithm was proposed.The user identification information was extracted,the hash mapping method was used to distribute user request,so that the same user continuous request was mapped to the same target server,and a dynamic adjustment strategy was designed for cluster size change.Experimental results show that the proposed algorithm can solve the service affinity and load balancing problem effectively,and stability and scalability of cluster systems is guaranteed.
