Abstract
A router includes at least two router modules, one of which is in an active state at any given time, the others being in a standby state, and a changeover capability making it possible to cause one of the other router modules to go from a standby state to an active state when the router module in the active state stops, each of the router modules having connections with one or more networks, and having at least one state machine, each state machine managing the interface associated with one of the connections. In the router, each of the router modules has data storage capability which, in the active state, enables it to store data relating to the state of the at least one state machine, when the machine is in a stable state, and data retrieval capability for retrieving the data when a changeover takes place.
