This reports the measured average jitter, in microseconds, from a completed delay-measurement test run, the actual result figure compared against the configured average jitter threshold. An admin uses this jointly with the delay figure to get a complete picture of path performance, since a circuit can have excellent average delay but still suffer from unacceptable jitter, or vice versa. For example, a service showing a low cienaCesCfmDelayMsgAverageDelay but an unexpectedly high cienaCesCfmDelayMsgAverageJitter would point to an intermittently congested hop causing variable queuing delay rather than a simple fixed propagation-delay issue.
