Abstract: A method for routing data in a computer network (1) including machines (2), routers (3) and controllers (4) defining routing rules and transmitting them to routers, comprising: storing by a controller in its database, of an identifier of a machine matched with an associated parameter including an identifier of the network segment associated with said machine and/or an identifier of a controller, for which the respective portion of the network which is associated with it, comprises said machine; transmitting by said controller to another controller of said set of information, and storing by said other network controller in its database, said set of information.
