Patent ID: 7916761

Claim:
A method for adding latency and jitter to a number of selected packets transmitted between end systems within a network of end systems, said method comprising: receiving a packet identifier, the packet identifier indicating a selected packet to which latency and jitter is to be added; receiving a latency value and a jitter value for the selected packet, wherein the jitter value is specified as a percentage of the latency value; receiving a packet; determining if the received packet is the selected packet; forwarding the received packet to its destination if the received packet is not the selected packet; and if the received packet is the selected packet, reading a real time clock; computing a transmit time for the received packet at least in part by multiplying a random number, the latency value for the selected packet, and the jitter value for the selected packet; and storing the received packet for later forwarding to its destination when the real time clock reaches the computed transmit time.
