Abstract

A method is disclosed for testing network devices for networks with a large traffic load utilizing one or more traffic load amplifiers to amplify the traffic load. The load amplifiers connected to the device may receive packets of an initial traffic load, multiply or copy the received packet, alter the destination address information in the header of the copied packets to generate packets with different destination addresses, and transmit the altered packets back to the device for further routing. The altered or copied packets may then be routed via the device back to the load amplifier for further amplification. Through this amplification process, a small initial load of packets may be amplified over and over by the load amplifiers until a target traffic load is achieved at the device to test the device performance at a large traffic load.
