US Patent 10439920 Network performance monitoring

A network device may include one or more processors configured to receive a measurement message en route to a destination via a network, where the measurement message includes a test packet of a two-way active measurement protocol (TWAMP) session. The network device may determine information based on the measurement message. The information may include a timestamp identifying a time associated with the measurement message, and may identify the measurement message. The network device may store or provide the information for determination of network performance information regarding the network device. The network device may transmit the measurement message toward the destination.
