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 such 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.
