Network-based application-independent time-error and direct port latency measurement
A system is proposed by which a link partner on a path with known latency and asymmetry can directly observe the time error of the attached slave PTP device, including offset from master as well as ingress and egress latency on the port. A qualified system implementing the proposed solution can provide application-independent real-time network based monitoring to assess a time sensitive networks / cyber-physical system's quality of time at the monitored slave nodes.
