Abstract: A method, a computer program product, and a computer system for monitoring conversational audio quality of Voice over Internet Protocol (VoIP) are provided. A monitoring system determines a size of an audio file and an available bandwidth. The monitoring system predicts time of receiving the audio file, based on the size and the bandwidth. The monitoring system determines whether the time of receiving the audio file exceeds a monitoring timer interval by a certain threshold. The monitoring system uses an intrusive testing method for monitoring call quality, in response to determining that the time of receiving the audio file exceeds the monitoring timer interval by the certain threshold.

Abstract: A self-organizing internet protocol television (IPTV) grid system that: establishes an internet protocol television grid including an IPTV server, a plurality of grid nodes, a first end user device and a second end user device; communicates an IPTV channel signal over a first communication path that begins at the IPTV server and ends at the first end user device; communicates the IPTV channel signal over a second communication path that begins at the IPTV server and ends at the second end user device; determines that a quality issue condition exists for the channel signal as communicated to the second end user device; and responsive to the determination of the quality issue condition, communicates the IPTV channel signal over a third communication path that begins at the first end user device and ends at the second end user device.

Abstract: In one embodiment, the quality of experience for a multi-part conference call is determined. Values for network characteristics for a conference call between at least three parties is captured using a multi-party conference call system. The network characteristics encompasses at least parameters expressed in an E-Model R-Factor equation. A quality of experience (QoE) is determined that accounts for degradation effects. The determined QoE is represented as a corrected mean opinion score (MOS) perceived by the receiving party. A controllable parameter of the conference call is dynamically and automatically modified to positively affect the determined QoE of the receiving party when the QoS is below a designated minimal QoE threshold.
