CA 2600546

A method or apparatus for managing monitoring of packet data traffic of a packet switched telephony trunk connection, such as an IP trunk, wherein the data packets identify ports but monitoring is based on extension lines and the like. A mapping unit is used for obtaining mapping data that relates ports to respective individual connections or extension lines. A packet duplication unit copies data traffic from the trunk, and an associative access unit either stores or allows direct use of the data via the mapping information.

La présente invention concerne un procédé ou un appareil pour gérer la surveillance de trafic de données en paquet d'une liaison téléphonique longue distance en téléphonie à commutation de paquets, notamment une liaison longue distance IP, les paquets de données identifiant les ports, la surveillance se faisant toutefois à base de lignes des postes et analogues. Une unité de mise en correspondance sert à l'obtention de données de mise en correspondance qui établissent les relations des ports avec les différentes connexions ou lignes de poste. Une unité de duplication de paquets recopie le trafic de données provenant de la ligne longue distance, et une unité d'accès associative stocke ou permet l'utilisation directe des données via l'information de mise en correspondance.
