Problems solved by technology

Telepresence protocols typically rely on fixed / static size buffers for network communication, if these buffers are incorrectly sized, this can lead to either insufficient network utilization or excessive queuing in the network, both of which negatively affect user experience

Abstract

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.

Description

technical field [0001] The present invention relates to end-to-end transmission quality detection, and more particularly to methods and systems for accurate, bounded, real-time detection of current network conditions when working with telepresence protocols such as RDP. Background technique [0002] A remote computing system may enable users to remotely access hosted resources. A server on a remote computing system may execute the program and send signals indicative of a user interface to clients connectable by sending signals over a network conforming to a communication protocol such as the TCP / IP protocol. Each connecting client may be provided with a telepresence session, ie, an execution environment including a set of resources. Each client can send a signal to the server indicative of user input and the server can apply the user input to the appropriate session. Clients can connect to server resources using a remote presentation protocol, such as Remote Desktop Protoc...
