Abstract Abstract
The One-Way Active Measurement Protocol (OWAMP) and the Two-Way The One-Way Active Measurement Protocol (OWAMP) and the Two-Way
Active Measurement Protocol (TWAMP) are used for performance Active Measurement Protocol (TWAMP) are used for performance
monitoring in IP networks. Delay measurement is performed in these monitoring in IP networks. Delay measurement is performed in these
protocols by using timestamped test packets. Some implementations use protocols by using timestamped test packets. Some implementations use
hardware-based timestamping engines that integrate the accurate hardware-based timestamping engines that integrate the accurate
transmission timestamp into every outgoing OWAMP/TWAMP test packet transmission timestamp into every outgoing OWAMP/TWAMP test packet
during transmission. Since these packets are transported over UDP, during transmission. Since these packets are transported over UDP,
