Abstract: Method and test device for performing testing in a network conveying a plurality of traffic flows. At the test device, receiving traffic flows through a first interface of the test device on a first segment and forwarding the received plurality of traffic flows towards a second segment of the network through a second interface. At the test device, receiving a test request directed to an address of a test module and, in response to the test request, causing a sequence of proprietary traffic to be injected on the second segment. A reprogrammable test device comprising a networked test module at least in part on a reprogrammable partition of a programmable logic device and a reprogramming module, on a static partition of the programmable logic device, for reprogramming at least a portion of the reprogrammable partition implementing the test module in accordance with reprogramming data received at the test device.

Abstract: A test system and a related method, the system comprising a test processing agent and local test device(s). The test processing agent processes test measurements related to a network-under-test into test results. The test processing agent is decoupled from the network-under-test, e.g., by being reachable through a network communication link distinct from the network-under-test. The local test device comprises a firmware module and a network interface (NI) module. The firmware module depends on external instructions for initiating a test sequence on the network-under-test. The NI module comprises at least one physical port connectable to the network-under-test. The physical port is used for initiating the test sequence. The test processing agent receives the test measurements following the initiation of the test sequence by the local test device and allows access to the test results.

Abstract: Systems and methods e to automatically analyze and display results of tests of a link include obtaining data from one or more tests of a link, wherein the data includes samples for Antenna Carriers (AxC) for one or more AxCs auto-detected on the link; processing the data to detect peaks on any of the auto-detected AxCs on the link; performing an analysis of any detected peaks to identify any issues on the link; and causing display of a user interface that includes a reporting of any identified issues with the user interface including a display of the identified issues and a spectrum graph.
