HOTS: An OWAMP-Compliant Hardware Packet Timestamper
Accurate timestamps on both the sender and the receiver side are crucial for one-way delay (OWD) measurements. Traditionally, the methods of (i) peering with NTP servers, and (ii) connecting to a time source directly, have been used to maintain the accuracy of a measurement system clock. However, it has became clear that such methods suffer from errors to different extents.
