Patent ID: 8755411

Claim:
A method to measure de-jitter buffer performance, comprising: 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 de-jitter buffer size, an upper de-jitter buffer size, a de-jitter buffer expansion speed, or a de-jitter buffer contraction speed based on the recorded signal and the known signal; comparing the one or more of the lower de-jitter buffer size, the upper de-jitter buffer size, the expansion speed, or the contraction speed to a performance requirement; and correcting communication network performance based on the comparison, wherein determining the expansion speed comprises: filling a lower portion of the de-jitter buffer; adding first jitter to the plurality of packets, the first jitter increasing at a first rate; and identifying the expansion speed as the first rate if no packet loss occurs.
