Audio and Video Quality Information

If audio and video devices are connected through a switch to a network with audio and video traffic, the switch can monitor the setup and termination of sessions for media streams transmitted over SIP. Switches can also obtain audio quality parameters through Enhanced Media Delivery Index (eMDI) instances and detect dynamic indicators of media streams, thereby implementing real-time monitoring of session packets on network nodes and fast demarcation of faulty network segments. Then, switches can calculate the mean opinion scores (MOSs) of media streams based on the data packet loss rate monitored through the eMDI instance and the size of the largest packet lost in the specified period. Finally, the switches report the KPIs and MOSs of media streams monitored by eMDI to the analyzer using telemetry technology.
