WebNov 26, 2024 · All gPTP protocols are layer 2 (Ethernet), which greatly reduces complexity for hardware or logic-based solutions. It eliminates the path delay mechanism in favor of the peer delay mechanism and it mandates that all bridges in the path between a time-aware device and the GM must be time-aware (i.e. provide transparent clock functionality). WebAllows complete testing of gPTP Correction Field, Neighbor Rate ratio and CSRO (Cumulative Scaled Rate Offset). Can use integrated packet impairments to verify gPTP …
