WorldFIP总线MAC子层的DSPN建模

DSPN Model of WorldFIP MAC Sub-layer

应用确定与随机Petri网DSPN对WorldFIP总线通信过程进行精细的建模。首先,介绍WorldFIP总线的集中介质访问控制MAC通信机制;其次,根据微周期内周期窗口的情况,分别应用DSPN建立基于相等周期窗口和不等周期窗口的WorldFIP总线MAC子层的通信过程模型。

A detailed DSPN (deterministic and stochastic petri net) model of communication process for WorldFIP is constructed by in this paper. Firstly, the MAC mechanism of WorldFIP is introduced. Secondly, the DSPN models of WorldFIP MAC based on the same size cyclic window and the different size cyclic window are accurately constructed according to the characteristic of cyclic window in each microcycle respectively.
