Apparatus and method to efficiently use the PTP timestamp for one-way delay and delay variation measurement in IP networks

摘要

A method is implemented by a network device to establish a one-way active measurement protocol (OWAMP) 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 an OWAMP test session between the session-sender and the session-receiver.
