| 摘 要： | 从软件容错的角度出发,在基于网络的分布计算环境下,针对军事指挥系统及银行管理系统的特点,为了满足这些应用对可靠性的要求,以组通信为基础,采用进程复制技术,提出了一个嵌套式动态容错模型;进而提出了一个动态容错算法,该算法保证当主服务进程发生失效时,能够动态地选择一个新的主服务进程,并保证所有后备服务进程的状态保持一致.

| Abstract: | From the view of the software fault-tolerance, in the distributed computing environment based on the network, for the property of the military command system and bank management system and in order to satisfy the reliability requirement of these applications, based on the group communication technology and by using the process replication technology, in this paper, a nested dynamic fault-tolerant model and a dynamic fault-tolerant algorithm are proposed. When the primary service process crashes, this algorithm can dynamiclly select one of backup process as a new primary service process and assure the state of all backup service processes is consistent. |
