Network Communication Speed Comparison Chart

Posted by Kevin Miller on Fri, Jan 27, 2012 @ 08:45 AM

As the demand for faster speeds has grown rapidly over recent decades, new communications networking equipment and systems are constantly being developed to accommodate these requirements . A result of these efforts is a series of established networking protocols and terminology that are used to identify various speed thresholds and the related equipment.

The chart below is intended as a quick reference guide to help readers associate the various networking speeds with their respective protocol/service names.
