Abstract

This paper presents test results from several IEEE1588 Transparent Clocks (TC) under realistic network conditions. Imperfections are documented that may impact the end-to-end synchronization performance between Master Clocks (MC) and Slave Clocks (SC). To help service providers select and configure these devices to meet their synchronization performance needs, a new test methodology for characterizing TC performance under real-world conditions is presented. The ldquoCorrection Factor Errorrdquo test method is introduced which could serve as the basis for future IEEE1588 test standards for these devices.
