Patent ID: 8102776

Claim:
A method of processing information at a network testing device, the method comprising acts of: receiving, at the network testing device, a specification of a sequence of frames in a data stream to be transmitted from the network testing device, wherein the specification specifies at least two frames including a first frame and a second frame, and wherein the specification specifies a first interframe gap associated with the first frame and a second interframe gap, having a different length from the first interframe gap, associated with the second frame, wherein the first interframe gap specified in the specification is specific to the first frame and the second interframe gap specified in the specification is specific to the second frame, wherein the interframe gap associated with the first frame is different from the interframe gap associated with the prior frame; and storing the specification; determining a length of the sequence of frames stored by a frame sequence table and generated from the frame sequence table by a first simulated traffic source set and a second simulated traffic source set, by selecting among first integer multiples of a least common multiple of periods of the first simulated traffic source set, based on absolute difference sums of the first integer multiples, each of the absolute difference sums including a total of absolute differences between (i) a particular one of the first integer multiples and (ii) second integer multiples of periods of the second traffic source set; generating, at the network testing device, the first frame and the second frame to simulate different traffic sources; and sending, from the network testing device, the first frame and the second frame generated to simulate the different traffic sources.
