摘　　要：为了解决移动云计算系统中因链接断开和网络分区对服务可靠性的影响问题,提出一种基于服务副本管理和节点自适应配置的服务软件架构;其由通信中间件、监测系统、上下文管理器以及副本管理器组成;根据监测到的服务需求和节点信息,副本管理器通过一种自适应配置算法来激活或休眠节点,使任务能够在当前最适合的节点中执行,以此提高计算服务系统的可靠性;案例结果表明,该方案能够保证动态网络环境中的服务可靠性。In order to solve the problem of service reliability caused by link disconnection and network partitioning in mobile cloud computing system,a service software architecture based on service copy management and node self-adaptive configuration is proposed.It consists of communication middleware,monitoring system,context manager and copy manager.The replica manager activates or sleeps the node through an adaptive configuration algorithm based on the monitored service demand and node information,so that the task can be executed in the most suitable node currently,thereby improving the reliability of the computing service system.The case study shows that the scheme can guarantee the service reliability in the dynamic network environment.
