Abstract：Train Communication Network (TCN) is the substantial guarantee of reliable and safe operation of rail trains and is strict with performance of real-time ability, fault-switch time and reliability. Parallel Redundancy Protocol (PRP) and High-availability Seamless Redundancy (HSR) are introduced to realize zero-switch time on network fault station of TCN. Due to the characteristics of reparability, functional dependency, fault-tolerance and redundancy, Dynamic Fault Tree Analysis (DFTA) is proposed to analyze the reliability of PRP and HSR on TCN. Binary Decision Diagram (BDD) and Markov matrix are adopted to resolve static and dynamic fault tree so that the quantity of calculation is reduced. The reliability indexes of PRP, HSR and Rapid Spanning Tree Protocol (RSTP) are quantified and analyzed in detail. The analysis results show that the proposed PRP and HSR redundancy structure has increased 5 764 h and 5 269 h respectively compared with RSTP, which effectively improves the network reliability.
