Requirements on the degree of accuracy in latency measurements are changing. As telecommunications standards continue to evolve with the rising demands of today’s consumers, so too do the latency and accuracy requirements of each consecutive generation of network technologies.

This white paper goes into deep technical detail around both the practice of and the benefits derived from hardware timestamping in Linux-based software for network service quality measurements. Data from network interface hardware datasheets is compared with actual measurement results. The research was carried out from a Linux measurement application using hardware timestamping in conjunction with the reflector-based Two-way Active Measurement Protocol (TWAMP). The white paper also provides a short overview of how hardware timestamping can be used in virtual machines (VMs).
