The invention concerns a router associated to a secure device (DC) and included in a communication network (RC), comprising an interface (IRT) to communicate with the secure device following an authentication of the router by the secure device, and comprising a protocol interpreter (INT) to command the execution of the critical operations of one or more routing protocols by the secure device. The sensitive or critical portions of a routing protocol are executed in a secure and reliable manner in the secured device, for example of a chip card type.

Router associated to a secure device

To monitor the functioning of the services of a first infrastructure (CI) upon which the functioning of the critical services of a second infrastructure (CI) depend, a server (SS) capable of communicating with both infrastructures receives, upon the detection of a failure of a service of the first infrastructure by a first terminal (CT) included within the first infrastructure, an identifier (SI) for the faulty service sent from the first terminal. The server transmits a request to the first terminal in order to retrieve the characteristics settings values of the faulty service, and apply correlation rules to the retrieved values in order to produce information relevant to the functioning of the faulty service. The server transmits a message (SPM) containing the produced information to a second terminal (CT) included within the second infrastructure, so that the second infrastructure can react to the failure of a service of the first infrastructure.
