Abstract
The present disclosure relates to a method for determining a size of a buffer of a device-under-test, DUT, which is transmitting data. The method comprises the steps of: transmitting a data stream with a transmitting bit rate by means of the DUT, wherein the data stream is loaded into the DUT buffer during said transmission; receiving the data stream with a receiving bit rate at a receiver device; detecting a difference between the transmitting bit rate and the receiving bit rate over time; monitoring a packet loss at the receiver side; detecting a time at which a packet error rate, PER, at the receiver side increases above a threshold based on the monitored packet loss; and calculating a size of the DUT buffer based on a difference between an amount of data transmitted by the DUT and an amount of data received by the receiver device from the start of the transmission until the detected time of the PER increase.
