Percentage of tiles that are discarded instead of sent to a remote peer (for example, from the MCU to a viewer). FrameLoss is only used for classifying inbound non-H264S streams. The average includes frames recovered from network losses. Packet loss rate after FEC has been applied aggregated across all video streams and codecs.Ī VBSS stream is marked as Good or Poor based on the value of the first available metric in the following order: Step #Ĭodec is NOT H264SAndStreamDirection is InboundIf FrameLoss > 50%Īverage percentage of video frames lost as displayed to the user. Step #Ī Score between 0 and 1 that is generated based on a combination of user experience, freeze duration statistics and overall call experienceĪ video stream is marked as Good or Poor based on the value of the first available metric in the following order: Step #Īverage percentage of video frames lost as displayed to the user. This classifier is available for Microsoft Teams product only. The video stream is marked Good or Poor based on the value of a classifier score generated to estimate that the end user experienced Frozen Video. Details available in RFC3550.Īverage jitter for stream in milliseconds. If one or more of the following conditions are met and Packet Utilization is > 500 packets, an audio stream is marked as Poor: MetricĪverage round-trip network propagation time, computed in milliseconds. For more information on these dimensions, see Dimensions and measures available in Call Quality Dashboard. CQD's "Poor Due To" dimensions can be used to understand which metric is responsible for a Poor classification. The metrics and conditions used to classify stream are shown in the tables that follow. Streams in CQD are classified as Good, Poor, or Unclassified based on the values of the available key quality metrics. To learn more about CQD and how to set it up, see Set up Call Quality Dashboard. This topic provides detailed information about the quality classification of media streams. The Call Quality Dashboard (CQD) for Microsoft Teams and Skype for Business Online allows you to gain insights into the quality of calls made using Microsoft Teams and Skype for Business services.
