•
Clock Jitter – is defined as the root-mean-square (RMS) average of the most recent offset
differences, and it represents the nominal error in estimating the offset (of the clock).
•
Clock wander – is the RMS of exponentially weighted frequency differences. This is not used
directly, but can, along with the jitter, be a highly useful monitoring and debugging tool.
•
Stratum – the level of each server in the hierarchy is defined by a stratum number. Primary
servers are assigned stratum one.
