  • Jitter buffer emulation for RTP streams in passive network monitoring systems
    Patent number: 9237108
    Abstract: A method for emulating a jitter buffer by a telecommunications network monitoring probe includes determining an RTP timestamp for each of the plurality of received RTP packets. An actual time of arrival is determined for each of the plurality of RTP packets. An expected time of arrival is determined for each of the plurality of RTP packets based, at least in part, upon a difference between the RTP timestamps of successive RTP packets. One or more of the plurality of RTP packets is discarded from the jitter buffer if the actual time of arrival is greater than the expected time of arrival for the one or more RTP packets.
