Claim Text:
1. A method of generating network traffic in a network device of a data communication network, the method comprising: providing traffic generation parameters in the network device that describe a desired traffic pattern to be generated by the network device, wherein the traffic generation parameters comprise a load factor for a Markov modulated Poisson process that describes a level of traffic of the desired traffic pattern to be generated by the network device; generating a trigger packet in the network device, the trigger packet specifying a drop precedence for packets generated by the network device in a state defined by the trigger packet; replicating the trigger packet a plurality of times to provide a packet train comprising a plurality of replicated instances of the trigger packet; selectively dropping one or more packets in the packet train based on the drop precedence specified in the trigger packet, wherein selectively dropping the one or more packets in the packet train comprises passing the packet train through a weighted random early discard queue that is configured to selectively drop and/or mark packets based on a drop probability that is related to the specified drop precedence, the drop probability being derived from the load factor; and transmitting the packet train without the dropped one or more packets from the network device.
