【摘要】 在Web应用日益普及的今天,Web服务器承担的任务越来越繁重,特别是进行大数据量的计算时,服务器的硬件资源成了计算效率的瓶颈。为了解决这一问题,结合云计算和中间件的技术特点,提出了一种基于多Agent的云服务中间件的体系架构,该框架分为用户接口层、SOA层和资源管理层3个层次,内部采用多Agent技术。节点间通过ACL消息进行通信,负载均衡采用静态计算能力与动态负载相结合,内置的日志服务和容错服务保障系统稳定运行。将此框架应用到实际Web应用中可以大大提高Web服务器的计算效率。更多还原

【Abstract】 On today when Web application is more and more popular,Web server undertakes tasks increasingly onerous,especially for the calculation of the large amount of data,the resource of the server’s hardware becomes bottleneck of the efficiency of computation. To solve the problem,combined with Cloud Computing and middleware technologies,this paper proposes an architecture of cloud services middleware based on multiAgent,the framework is divided into three levels such as user interface layer,SOA layer and resource management level,using multiAgent technology inside. Nodes communicate with each other by ACL messages. Load balancing combines static compute ability with dynamic load,the builtin log service and faulttolerant service guarantee stability of the system. This framework is applied to actual Web applications. It can greatly improve the computational efficiency of the Web server.更多还原
