中文摘要：

为揭示高完整性和标准完整性配置下时钟同步容错方法的有效性,对时间触发以太网（time-triggered Ethernet,TTE）网络标准中时钟同步服务描述进行协议分析,还原时钟同步算法的理论模型。通过分析容错机制对应的失效模式,对TTE网络时钟同步算法在单同步域下对抗失效的有效性进行仿真验证,仿真结果表明了高完整性配置下的TTE网络时钟具备对抗单点随意失效的能力。

英文摘要：

To clarify the effectiveness of fault-tolerant clock synchronization in high-integrity and standard-integrity devices, the normative description of clock synchronization services in the time-triggered Ethernet （TTE） standard was analyzed, and the theoretical model for this clock synchronization algorithm was rebuilt. With the analysis of failure modes that certain fault-tole- rant mechanisms fight on, and referring to the performance evaluation of the clock synchronization algorithm against failures in a single synchronous domain of a TTE network, computer simulations were carried out. The fact that synchronized clocks in high- integrity TTE networks can deal with any arbitrary single-failure disturbances was verified.
