Gptp correctionfield
WebgPTP systems, as gPTP timestamps the messages right after the start of frame delimiter (c.f. [5]). At the end of the message exchanges, the delay requester knows all four timestamps (t 1, t 2, t 3, and t 4) that it reads from the exchanged messages. The propagation delay is calcu-lated using Eq.1. The delay equals half of the di erence of the ...
