Patent ID: 10063449

Abstract:
A method is implemented by a network device to establish a one-way active measurement protocol (OWAMP) test session that supports use of a Network Time Protocol (NTP) timestamp format and a Precision Time Protocol Version 2 (PTPv2) timestamp format. The network device acts as a control-client that communicates with a server to establish an OWAMP test session between a sender and a receiver. The method includes receiving a server greeting message from the server indicating timestamp formats that the receiver can interpret, checking whether the receiver supports the multiple timestamp format extensions to OWAMP, configuring the sender to set timestamps in a format that the sender can set and the receiver can interpret if the receiver supports multiple timestamp format extensions to OWAMP, sending an extended set-up-response message to the server indicating a timestamp format that the sender can set and the receiver can interpret, and receiving a server-start message from the server.
