Table 5-10 Video QoS - Stream results, Stream Metrics tab
Result Description
Frames Total number of frames received, by type.
Lost Total number of packets lost containing data for the respective frame type; for
example, the total number of packets lost containing I-frame data. These results
are packet counts, not frame counts.
NOTE: If packets for one frame type show an inordinate amount of loss
compared to others, there may be a problem with network congestion
and/or configuration. For example, some NEs may be configured to
discard video B-frame data during periods of heavy congestion.
