With the technical development of the on-board subsystems, there has been in parallel a demand for more reliable and powerful networks.
The network is really the frame on which the most advanced systems are assembled, supporting the transfer of multimedia information and all necessary data information to integrate everything on a train.
Networks need to provide a high bandwidth and capability to manage all the information that the other SEPSA’s onboard systems handle : Communication systems, Control systems, Passenger Information systems and Security systems, as well as other third party systems.

The particularities of the network of a train, when being a composition of vehicles which are in motion, make it should be able to handle the traffic and avoid IP conflicts, even if the train composition is reordered and physically modified .
