Elements of the PTP Graph
The PTP graphs are useful in observing the effects of traffic on the PTP
messages and the operation of transparent and boundary clocks. Non-PTP
aware switches may have significant PTP delay variations, while transparent
and boundary clocks will have much less variation and total delay. (See
Figure
162
.)
