Abstract: A system for monitoring calls in a VoLTE network is provided. The monitored calls include SIP, RTP and H.248 portions. The system includes monitoring probes and first and second correlation engine components (CECs). The probe is configured to generate SIP, RTP and H.248 data records (DRs), send the SIP DRs to a second CEC based on a distribution key, generate and send a routing label to a first CEC and to send the H.248 and RTP DRs to the first CEC based on the first and second attributes, respectively. The first CEC is configured to correlate the received RTP and H.248 DRs and the routing label based on the second and first attributes, respectively, and send the correlated DRs to the second CEC based on a distribution key. The second CEC is configured to bind all of the generated DRs to a single call based on the distribution key.

Abstract: A method for monitoring streaming video content is provided. Content Delivery Network (CDN) feed sent over one or more CDNs is monitored and analyzed using a first soft probe deployed in the one or more CDNs to generate a first video session record. Video traffic sent over a packet core network (PCN) is monitored and analyzed using a second soft probe deployed in the PCN to generate a second video session record. A third session record is generated by correlating the first session record to the second session record. The third session record corresponds to an end-to-end video streaming session. One or more performance characteristics corresponding to the end-to-end video streaming session are generated based at least in part on the third session record.

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.

Abstract: The embodiments described herein relate to obtaining one or more measurements from a VOIP communication that is indicative of call quality, changing one or more settings of the VOIP communication, such as the type of codec or the ascribed bit rate of a VBR codec, and determining call quality of the VOIP communication after setting changes by utilizing at least one of the one or more call quality measurements.
