DETECTION OF END-TO-END TRANSPORT QUALITY

摘要

In various embodiments, methods and systems are disclosed for the real time detection of network conditions in conjunction with a remote presentation protocol. The link quality may represent the quality of the end-to-end connection between client and server with upper and lower bounds on the injection of additional traffic used for measurement. In some embodiments, the measurement technique may be selected based on the type of measurement that is desired. Accuracy may be maintained by selecting the type of measurement used based on current and previous network conditions. In one embodiment, a state model is used to determine the frequency of measurement and to determine when the measurements have produced a stable estimate of the link quality.

主权项

1. A system for determining link quality between the system and a computing device communicatively coupled over a communication network via a remote presentation session, the system comprising at least one processor programmed to cause, by the system:
selecting, during the remote presentation session, a type of link quality measurement; invoking a transmission measurement function based on said type of link quality measurement and determined link conditions; augmenting network data between the computing device with one or more measurement requests that are based at least in part on the transmission measurement function; determining a link transmission time based on at least one response to the one or more measurement requests; and determining, during the remote presentation session, a link quality based on the link transmission time.
