APPARATUS AND METHOD TO EFFICIENTLY USE THE PTP TIMESTAMP FOR TWO-WAY DELAY AND DELAY VARIATION MEASUREMENT IN IP NETWORKS

摘要

A method is implemented by a network device to establish a two-way active measurement protocol (TWAMP) test session to verify that a session sender and session reflector support a timestamp format extension including a Precision Time Protocol Version 2 (PTPv2) timestamp format. The PTPv2 timestamp format is to be utilized in place of a Network Time Protocol (NTP) timestamp format. The network device acts as a control-client that communicates with a server to establish the TWAMP test session between the session-sender and the session-reflector.
