An emulator to develop the Wire Train Bus protocol stack

Buses in modern trains must cope with dynamic on-board network topologies while ensuring that data are delivered in real time. This is the case of the wire train bus, in which most of the nodes are complex multi-processor gateways. In these systems, the link layer related tasks, as defined in the train communication network (TCN) standard, need all the power of a dedicated processor. However, the development of the firmware is prone to errors and misinterpretations of the text. To provide a robust development and verification environment, a TCN emulation application has been created. This program lets the developer create a virtual network to debug and test the TCN protocol stack and eventually, applications built on top of it
