论文摘要
我们提出了OSPF路由协议的三个正式模型。前两个是在定时过程代数T-awn中形式化的，该代数不仅是针对路由协议量身定制的，而且还指定了易于阅读的伪代码中的协议。两种模型之间的差异在于细节级别（抽象级别）。从更抽象的模型中，我们生成第三个模型。它基于定时自动机的网络，可以在模型检查器Uppaal中执行。
We present three formal models of the OSPF routing protocol. The first two are formalised in the timed process algebra T-AWN, which is not only tailored to routing protocols, but also specifies protocols in pseudo-code that is easily readable. The difference between the two models lies in the level of detail (level of abstraction). From the more abstract model we then generate the third model. It is based on networks of timed automata and can be executed in the model checker Uppaal.
