| 摘 要： | 从软件容错的角度出发 ,将组通信技术引入到主动复制技术中 ,以组通信中的虚拟同步机制为基础 ,提出一个新的基于协调者的主动复制协议。该协议保证 ,当协调者进程发生失效时 ,能够动态地选择一个新的协调者 ,并保证所有副本进程的状态是一致的 ;且该协议具有响应时间短、效率高等优点。

| Abstract: | From the software fault-tolerance view, we introduce the group communication technology to the active replication technology, propose a new dynamically active replication protocol based on a coordinator. When the coordinator is crashed, the protocol can dynamically select a new coordinator process and ensure the state of all the backup service processes are consistent. The advantage of the protocol is the short response time and high efficiency. |
