dc.description.abstract Ethernet use for control networks is an emerging topic of study. Research discusses the implementation of train control networks using Ethernet. In this research, an Ethernet Train Control Network for one wagon with a mixed communication load environment (real-time and non-real-time traffic) was simulated. Both the control and entertainment loads were implemented on top of Gigabit (GbE) Ethernet, each with a dedicated controller/server. Triple Modular Redundancy (TMR) implementation of the control network at the sensor level was tested. Results for the case of introducing on-board passengers’ entertainment (Wi-Fi and video streaming) were presented based on OPNET simulations. Additionally, the network model was further modified to have a control load with mixed sampling periods. It was shown that this system could tolerate the failure of one controller in one wagon. In a two wagon scenario, fault tolerance (FT) at the controller level was studied, and simulation results showed that the system could tolerate the failure of 3 controllers. The hybrid model scenario was successful in meeting the packet end-to-end delay with zero packet loss in all OPNET simulated scenarios. A supervisor was further interconnected to both wagons. Two fault tolerance analyses were presented by studying the reallocation of the control load according to the number of Servers failed. In the first analysis the supervisor was acting in a passive manner where it only acts when all the other Controllers/Entertainment Servers fail. The other analysis presented an active supervisor that acts once a Controller fail. The main measuring metric used is the maximum real-time control packet end-to-end delay and ensure it meets its constraints. All simulations are conducted on OPNET Network Modeler and results are subjected to a 95% confidence analysis. en
