Abstract
Systems and methods to measure the performance of a de-jitter buffer are disclosed. An example method includes transmitting a known audio signal via a plurality of packets over a packet-based network, recording a received signal based on the known audio signal, analyzing the recorded signal to determine one or more of a lower size, an upper size, an expansion speed, or a contraction speed of a de-jitter buffer based on the recorded signal and the known signal, comparing the one or more of the lower size, the upper size, the expansion speed, or the contraction speed to a performance requirement, and correcting communication network performance based on the comparison. Determining the expansion speed includes filling a lower portion of the de-jitter buffer, adding jitter to the plurality of packets, the jitter increasing at a first rate, and identifying the expansion speed as the first rate if no packet loss occurs.
