A time server of a server time protocol (STP) facility of a coordinated timing network (CTN) receives a primary-reference-time (PRT) update, with the primary-reference-time update having been determined with reference to a time source, which includes a precision-time-protocol (PTP) source. ...

and Delay Variation Measurement in IP NetworksA method is implemented by a network device to establish a two-way active measurement protocol (TWAMP) test session that supports use of a Network Time Protocol (NTP) timestamp format and a Precision Time Protocol Version 2 (PTPv2) timestamp format...
I'm implementing a precision time protocol PTP slave. For this I have to make a real time clock with adjustable speed. To realize this i increas the real time clock with a timestep at each clock cycle. Furthermore i measure elapsed time intervals at the PTP Master an...
Other time protocols, such as “Time Protocol” (RFC-868) and “Daytime Protocol” (RFC- 867) are used to set computer clocks, but are not optimized as precision time distribution systems. NTP, SNTP, and eventually PTP, are preferred for IED synchronization. ...
(U-87 MG) cells. Then, we reported that the expression of these miRNAs is (i) strongly affected in patients with glioma compared to that in a non-tumoral brain; (ii) correlated with the histology/grade of glioma according to the 2016 WHO classification; and (iii) predicts the overall ...
