The device for access control between ATM networks, comprises signaling analysis means (4) and traffic analysis means (20, 21) linked to an ATM switch (3) configured so as to steer via the signaling analysis means, ATM signaling messages exchanged between internal and external ATM networks, and so as to steer via the traffic analysis means, traffic-bearing ATM cells exchanged between the internal and external networks within the framework of ATM connections established by means of said ATM signaling messages. Access control management means (7) dynamically configure the traffic analysis means (20, 21) as a function of an access control policy and of information gathered by the signaling analysis means (4) in such a way that the traffic analysis means filter each ATM cell in accordance with the access control policy. |
