Real Time Performance Analysis of CAN Bus Based on TimeNET

The real-time parameter is a key point of protocol's performance evaluation. The most important thing is to give an effective and reasonable method to simulation. Based on the analysis of the Data Link layer of CAN bus protocol, a deterministic stochastic Petri nets model of MAC sub-layer in CAN bus protocol is built , aiming at the real-time performance analysis. Also a calculation formula is given combined with the actual example.
