Can Ethernet switches be designed to avoid the effects of these
fluctuations?
A switch can be designed to support IEEE 1588 while avoiding the effects of queuing. In this case two
modifications to the usual design of an Ethernet switch are necessary:
1.
The
Boundary Clock and Transparent Clock
functionalities defined by IEEE 1588 must be implemented
in the switch.
2.
The switch must be configured so that it does not pass IEEE 1588 message traffic using the normal
communication mechanisms of the switch.
Such an Ethernet switch will synchronize clocks directly connected to one of its ports to the highest possible
accuracy.
