Abstract :
In this study, OPNET simulations are run to study the performance of a single Gigabit Ethernet two-wagon train control network. The network carries both control and entertainment loads. Each wagon has two servers; a Controller to carry the control load and an Entertainment Server to carry the entertainment load. A passive supervisor is interconnected to both wagons. A fault tolerance analysis is presented; it is based on a specific reallocation of the control load. It is proven that the network can survive the failure of both Controllers and both Entertainment Servers. OPNET simulations indicated that the maximum real-time sensor-to-actuator packet end-to-end delay met its constraints and that there were zero packets dropped.
