  • Method and telecommunications system for monitoring a data flow in a data network
    Patent number: 7979529
    Abstract: The invention relates to a method and telecommunications system (SYS) for monitoring a data flow (DAT) in a data network (WWW) between at least two telecommunications terminals (TEA, TEB), which are connected to the data network via at least one access server (AAA, AAB). When monitoring, the data flow (DAT) between the telecommunications terminals (TEA, TEB) is rerouted from the access server (AAA, AAB) via a monitoring server (PRO), which makes a copy (KOP) of the data flow (DAT) and transmits it to an evaluation unit (ASW).
