ABSTRACT:
Network testing is conducted using a pair of traffic agents that acts as sender and receiver endpoints. The sending traffic agent generates and transmits a stream of packet batches, each batch being composed of high and low priority packets in a predetermined sending order. The receiving traffic agent analyzes the order of packet arrival in the stream relative to the sending order, and returns results to a traffic control module. Path speed and the priority classification of the traffic are parameters used to configure the tests. The tests are typically run periodically under different load conditions in order to evaluate the effects of other traffic being concurrently transiting the network.
