Abstract
Measuring delay in a network segment and/or through a network device is disclosed. A method includes a sender preparing a real-time transport protocol with a transmit timestamp based on the time received from a remote, well-known time server, and a receiver computing a one way delay based on a receive time obtained from a remote, well-known time server and the transmit timestamp. A method in a single system includes a sender preparing a real-time transport protocol with a transmit timestamp based on the system, and a receiver computing a one way delay based on a receive time obtained from the system and the transmit timestamp. The method may be performed on one or more network cards and in one or more network testing systems, and may be implemented by one or more computing devices.
