A system and method for network performance testing are developed. One system includes a control network device configured to send network test performance settings configure at least one data generator and network switches so that each data generator sends test data via a plurality of network entities such as network ports or cable modems, for example. The exemplary system further includes at least one data receiver for receiving the test data from the at least one data generator via the network entities and an entity under testing such as a cable modem termination system, for example. In one embodiment, when a data receiver receives the test data, the data receiver provides the received test data to the control network device that generates a test result record based on the test data received on the data receiver.
