  • Patent number: 7894356
    Abstract: A system and method for measuring network performance include a first element in a network, the first element operable to receive a data packet and to create a clone packet based on the data packet, the clone packet having a destination the same as a destination of the data packet and having information identifying the clone packet as a clone, the first element operable to insert the clone packet into a data stream with the data packet.
    Type: Grant

  • Publication number: 20070081467
    Abstract: Apparatus and method for testing of a telecommunications network, which uses a passive monitoring system to generate actual customer usage data concerning the telecommunications network. An active test manager uses the actual customer usage data to instantiate a set of test templates from a store of predetermined test templates, the test template describing a sequence of user actions performed in the network. The test templates include at least one test variable, which is updated by the active test manager, using the actual customer usage data, to generate a test, or set of tests. The generated test, or set of tests are then used by an active testing module to actively test the telecommunications network, hence the tests are updated using the latest data on customer usage.

  • Patent number: 6975617
    Abstract: The network monitoring system comprises a network router with built-in monitoring data gathering. The network router includes channels through which data pass in packets. Each of the packets includes a packet header. The network router additionally includes a header copier and a packet generator. The header copier generates a header copy from the packet header of at least some of the packets. The packet generator receives the header copies and forms monitoring data packets from them. Each monitoring data packet additionally represents temporal data relating to the header copies included in it. A method of obtaining performance data relating to a data transmission network that includes a node passes data through the node in packets. Each of the packets includes a packet header. At least some of the packet headers are copied to obtain respective header copies as monitoring data from which monitoring data packets are formed.
