• Loss Distance – Enter the Loss Distance threshold, in number of packets.
This triggers when RTP losses cause a RTP LD Error.“Loss
Distance” measures the difference in sequence numbers of
two loss events, with a “loss event” being the loss of one or
more packets in a row. So for the following stream (1 x 3 4 5
x x 8 9 10) the loss distance between the two events is 4. If
the loss distance is less than the configured threshold, then
the “Loss Distance Error” statistic will increment.
• Loss Period – Enter the Loss Period threshold, in number of packets.
This triggers when RTP losses cause a RTP LP Error.“Loss period”
is the length of a single loss event, that is, the number of lost
packets between two successfully received packets. So for the
following example stream (1 xxx567xx10x12), there are three
loss periods, with lengths of 3, 2, and 1.
