The invention relates to an IP communication architecture between a ground computer (1) connected to a main router (3) and a mobile computer (4) onboard a train and connected to a mobile router of said train. The architecture comprises at least one infrastructure including base stations (7b, 8a-b, 12a-c) equipped with a radio communication means and ground base routers (17, 18, 11a-c), connected to the infrastructure. Each mobile router comprises: a radio communication means adapted for establishing a wireless communication link with one of the base stations of the infrastructure, a storing means comprising IP addresses of base routers connected to the infrastructure, and a connection means for initiating a connection with a base router from said list of base routers once a wireless link is established. |
