Patent ID: 7773505

Claim:
A method for generating packet delay variation (PDV) with a uniformly distributed probability density function (PDF) for packet timing recovery stress testing of a network, comprising: receiving, by a PDV generator, a stream of packets, each packet generated at a regular interval by a packet generator; determining, by the PDV generator, a delay for each packet based on delay target values determined based on a pre-biased PDF comprising a uniform PDF that is pre-biased with a pre-bias transfer function; and transmitting, by the PDV generator, each packet over the network with the delay determined for that packet, wherein, for a uniformly distributed random number greater than or equal to zero, the pre-bias transfer function is based on an Nth root of the uniformly distributed random number, and for a uniformly distributed random number less than zero, the pre-bias transfer function is based on a negative of the Nth root of an absolute value of the uniformly distributed random number.
