| 摘要: |
| 时钟同步协议是时间触发网络的一个重要组成部分，是时间触发网络实时性和确定性的关键。本文基于扩展标记变迁模型对时钟同步协议进行建模，基于模型检测方法对协议是否满足正确性属性进行验证。验证结果证明了在不同启动场景下时钟同步网络协议的正确性，也表明了扩展标记变迁模型对于协议验证的有效性。 |

| Abstract: |
| Clock synchronization protocol, as an important component of the time-triggered networks, is the key to the instantaneity and certainty of the time-triggered networks. The modeling and verification of clock synchronization protocol were studied. The protocol′s behaviors were modeled by the extended labeled transition systems, and its correctness was verified by model checking technique. The verification results certified the correctness of this protocol even under different startup scenarios. Experimental results also show the effectiveness of extended labeled transition systems in protocol verification. |
