Abstract

A method for analyzing a streaming media session between at least two communicating entities includes at least one media stream having at least two packets communicated between the communicating entities during the streaming media session. At least two monitoring entities are configured to record a plurality of observations pertaining to at least one of: the media stream, the packets, devices associated with at least one of the communicating entities, wherein the monitoring entities include at least one of a network entity forwarding the media stream between the communicating entities. Observations are received from the monitoring entities, and processed to obtain a plurality of pre-processed observations. The pre-processed observations are analyzed to determine a session quality. A notification is sent to at least one of the monitoring entities during the streaming media session, if the session quality satisfies at least one quality criterion.
