文章在Byzantine fault tolerant状态机复制容错算法(BFT)中增加适应性失效检测。根据拜占庭容错服务应用需求和运行环境动态调整失效检测时间,适应性好,能满足BIT失效检测要求。当主复件失效时,可以缩短视图切换时间,减少系统响应时间,提高系统可用性。
The paper presents on adaptive failure detection in Byzantine-Fault-Tolerant replication algorithm. Adaptive failure detection can dynamically adjust the detector time to the requirements of applications and runtime environments. The requirements of BIT for failure detector are satisfied by the good failure detection. When the primary replica is failure, the performance of Byzantine-Fault-Tolerant service is improved by reducing time of view change.
