摘　　要：在组件冗余备份的前提条件下,提出一种基于连接迁移技术的服务自组织方法。该方法根据服务处理流程将系统组件分解为通信组件、服务分发组件、数据存储组件;备份组件将其生存性信息实时发送给工作组件,并获取最新服务状态列表,当某一组件生存性最高时,根据组件的功能及其在体系结构中的位置,通过多种连接迁移技术进行服务自组织。利用仿真实验验证了生存性计算的有效性;并通过在网络环境中搭建一个Web服务器证明:在攻击情况下该方法可以有效提高稳态和瞬时的服务可生存性。As a new direction in network security, the survivability of information systems is different from traditional network security. This paper presents a service self-organization method based on connection handoff. According to service processing flow, the system is divided into communication, service distribution, and service supply modules. Backup modules survivability information is send to online modules and gets the list of newest service states. When the survivability of a module is highest, the self-organization strategies are implemented using multi-handoff technology. The system possesses the merits such as transparency to users, flexibility and operability of the configuration. Experiments confirm that this method can enhance the quality of service and improve service survivability.
