Endace conducted a trial of the Precision Time Protocol (PTP), also known as IEEE Std 1588TM-2008, across a large corporate WAN. Clock synchronization was tested across an operational backbone. The goal of the trial was to characterize the performance of PTP as a method for providing time synchronization to sites that do not have direct access to external clock references such as GPS.
