Server-side reproduction of client-side quality-of-experience
Abstract:
A server distributing a stream to a client device may use server-side metrics to detect issues that interrupt or otherwise affect playback of the stream by the client device. The server reproduces the issues experienced by the client device from the server-side metrics without accessing or using client-side metrics. The server-side metrics may include data that may be produced or obtained by the server such as requested stream segment filenames that identify changes in the stream bitrate, and timestamps at which the client device requests different segments. The client-side metrics may include metrics that are produced by the client device, and that directly identify the same client-side issues the server reproduces via the server-side metrics. The server or a distributed platform in which the server operates may dynamically alter the delivery of the stream or perform other remedial actions if the server detects various client-side issues from the server-side metrics.
