CA 2277382

A method and apparatus for monitoring data sent between a source node and destination node in a switched network, wherein the switches configure themselves to establish a connection path to a probe switch to receive the monitored data. The source and destination are identified along with the probe switch. An originating switch on a path between the source and destination is identified and connections between the originating switch and the probe switch are established. The originating switch sends out a first message and when the probe switch receives the first message, it returns a second message to the originating switch. Each switch between the originating switch and the probe switch that receives the first and second messages configures itself to establish the connection path.

L'invention concerne un procédé et un appareil de contrôle de données envoyées entre un noeud de source et un noeud de destination dans un réseau commuté, dans lesquels les commutateurs se configurent pour établir une voie de connexion à un commutateur sonde afin de recevoir les données contrôlées. La source et la destination sont identifiées avec le commutateur sonde. Un commutateur de départ dans une voie entre la source et la destination est identifié et des connexions entre le commutateur de départ et le commutateur sonde sont établies. Le commutateur de départ envoie un premier message et lorsque le commutateur sonde reçoit le premier message, il renvoie un second message au commutateur de départ. Chaque commutateur entre le commutateur de départ et le commutateur sonde recevant les premier et second messages se configure pour établir la voie de connexion.
