Bandwidth graph
By clicking the BW:MLR button the graph displays the peak bandwidth as a function
of time. The negative part of the composite graphs is still the packet loss (i.e. the
MLR).
If the stream contains a transport stream (mapping TS/x) the bitrate corresponds to
the Mon parameter Net bitrate (i.e. bitrate excluding null packets). Otherwise the
bitrate is the UDP payload bitrate corresponding to the Mon parameter Curr bitrate.
The bandwidth error threshold is configured in the Ethernet - Ethernet thresh.
menu.
RTP graph
By clicking the IAT:RTP button the graph displays the packet jitter as a function of
time. The composite graphs displays the RTP packet loss below the X-axis. If the
monitored stream is not RTP encapsulated, IAT will be represented by grey colour and
there will never be any indication of packet loss in the graph.
