6: Basic Parameters For jitter probes, positive (increasing latency) and negative (decreasing latency) statistics are shown, as well as the number of positive or negative jitter samples in each direction, and the sum and (and sum squared) of the positive or negative jitter times. These numbers give a summary of how much variation there was in latency times and if the variation was small or large.

For jitter probes, positive (increasing latency) and negative (decreasing latency) statistics are
shown, as well as the number of positive or negative jitter samples in each direction, and the sum
and (and sum squared) of the positive or negative jitter times. These numbers give a summary of
how much variation there was in latency times and if the variation was small or large.

Error Conditions
The following error conditions are detected by the probes. Except where noted, the RTT results for
a packet with errors will not be counted in the accumulated statistics.
Error Condition
Description
Timeout
A response was never received for the packet. These packets are listed as
Lost Packets under the accumulated statistics.
Late Arrival
A response was received for a packet, but the response was received after
the timeout configured for the probe. The SLC will wait at most 2 times the
probe's timeout for late arrival packets. The RTT results will be included in
the accumulated statistics.
