摘要： Embodiments of the present invention provide a method, system and computer program product for multi-scale network traffic generation. In one embodiment of the invention, a network traffic generation method can be provided. The method can include defining multiple, different scales in an n-state MMPP model to accommodate a full characteristic response of a modeled traffic scenario. The method further can include establishing a transition window for each of the scales and determining a state through the transition window for selected ones of the scales. Finally, the method can include computing an inter-packet time according to the determined state for each of the selected ones of the scales and generating and transmitting packets for the selected ones of the scales utilizing a correspondingly computed inter-packet time.

摘要： Aspects of the invention provide an improved solution for processing packets in a packetized communications network. For example, a next packet in a set of incoming packets placed in a plurality of queues is selected by obtaining a random/pseudo-random search key and identifying one of the plurality of queues based on the search key and a Patricia tree that includes at least one child node for each of the plurality of queues. A greedy algorithm can be used to select an alternative queue should the first selected queue be empty.
