论文摘要
灵感来自使用共识或其他协议协议进行全局协调的分布式应用程序，我们为参数化系统定义了一个新的计算模型，该模型基于一般的全局同步原始原始词，并允许全局过渡守卫。我们的模型概括了文献中的许多现有模型，包括广播协议和受保护协议。我们表明，对于没有警卫的系统，可及性能是可以决定的，并且在守卫存在下提供了足够的条件。此外，在许多受我们目标应用程序启发的情况下，我们调查了可及性能的截止，并为小截止值提供了足够的条件。
Inspired by distributed applications that use consensus or other agreement protocols for global coordination, we define a new computational model for parameterized systems that is based on a general global synchronization primitive and allows for global transition guards. Our model generalizes many existing models in the literature, including broadcast protocols and guarded protocols. We show that reachability properties are decidable for systems without guards, and give sufficient conditions under which they remain decidable in the presence of guards. Furthermore, we investigate cutoffs for reachability properties and provide sufficient conditions for small cutoffs in a number of cases that are inspired by our target applications.
