    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 change in an optimum video size for a streaming video. The method may also include determining one or more constraints of resizing associated with the change in the desired video size. The method may further include adaptively resizing the streaming video to a current desired video size when the one or more constraints of resizing exceed a threshold value.

    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： 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： An approach is provided for predicting system performance. The approach predicts system performance by identifying a Queuing Network Model (QNM) corresponding to a clustered system that handles a plurality of service demands using a plurality of parallel server nodes that process a workload for a quantity of users. A workload description is received that includes server demand data. Performance of the clustered system is predicted by transforming the QNM to a linear model by serializing the parallel services as sequential services, identifying transaction groups corresponding to each of the server nodes, and distributing the workload among the transaction groups across the plurality of nodes. The approach further solves analytically the linear model with the result being a predicted resource utilization (RU) and a predicted response time (RT).
