| 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. |
