摘要： A computer-implemented method, computer program product, and computing system is provided for managing quality of experience for communication sessions. In an implementation, a method may include determining a participant focus metric for each of a plurality of participants of a communication session. The method may also include identifying one of the plurality of participants of the communication session as having sufficient capacity to support the communication session based upon, at least in part, the participant focus metric for each of the plurality of participants of the communication session. The method may also include selecting the one of the plurality of participants having a sufficient capacity to support the communication session as a selected focus for the communication session. The method may further include adaptively implementing a centralized communication session architecture utilizing the selected focus.

摘要： A primary video and a second instance of a reference video can be simultaneously transmitted to a system through at least a first node of a communication network, the second instance of the reference video configured to be compared to a first instance of the reference video stored by the system to generate at least one quality of experience (QoE) value that infers a perceptual quality of the primary video as received by the system. The QoE value can be received from the system. A determination can be made as to whether the QoE value is less than a threshold value. Responsive to determining that the QoE value is less than the threshold value, the perceptual quality of the primary video can be improved by re-routing transmission of the primary video to the system.

摘要： An approach is provided for predicting system performance. The approach operates by identifying a Queuing Network Model (QNM) corresponding to an information technology (IT) environment that includes a number of servers that perform a plurality of parallel services. The QNM is transformed to a linear model by serializing the parallel services as sequential services. Hardware based service demands are retrieved from the system. Software-based service demands are inferred from the hardware-based service demands. Predicted performance results of the IT environment are calculated based on the hardware-based service demands, the software-based service demands inferred from the hardware-based service demands, and the system transaction rate of the system.

摘要： A computer-implemented method, computer program product, and computing system is provided for managing quality of experience for video conferences. In an implementation, a method may include determining a capacity of a participant associated with a video conference. The method may also include determining a number of remote participants of the video conference. The method may further include implementing a video distribution architecture for the participant based upon, at least in part, the capacity of the participant and the number of remote participants. Implementing the video distribution architecture for the participant may include implementing a distributed architecture session for the participant if the capacity of the participant is greater than or equal to the number of remote participants of the video conference. Implementing the video distribution architecture for the participant may also include implementing a centralized architecture session for the participant if the capacity of the participant is less than the number of remote participants of the video conference.

摘要： A method for calculating a mean opinion score (MOS) during an ongoing Voice over Internet Protocol (VoIP) call is provided. The method may include determining a time delay between a VoIP source and a VoIP destination connected by a communications network. A start recording message is sent from the VoIP source to the VoIP destination. A first recorded call sample from the VoIP source and a second recorded call sample from the VoIP destination are generated, whereby the first and the second recorded call sample are generated with a recording delay value corresponding the determined time delay for synchronizing the first and the second recorded call sample. Using an intrusive call quality measurement, a first MOS value is calculated based on the first and the second recorded call sample. Using a non-intrusive call quality measurement, a second MOS value is calculated based on the first MOS value.

摘要： A first instance of a reference video is stored. A primary video and a second instance of the reference video are simultaneously received. At least one quality of experience value that infers a perceptual quality of the primary video as received by a system is generated by comparing the first instance of the reference video to the second instance of the reference video on a pixel-by-pixel, frame-by-frame, basis and determining whether each pixel and each frame contained in the first instance of the reference video are contained in the second instance of the reference video.
