A recent white paper from Juniper Networks focuses on Ethernet switches, with the goal of helping technicians gain insight into the various ways that latency can be measured, and to understand the various testing methodologies.

"While many people understand the definition of latency, what some do not know is that measuring latency on a switch is not an exact science," states the document's introduction. The discussion contends that "it is important to understand how latency can be measured so that users have a better insight and understand how best to apply the information in order to make an informed decision when selecting a switch for their LAN infrastructure."
