NetTime - Network Time Synchronization Tool

WebJan 9, 2024 · The ECUs on network protocols (CAN, Ethernet, FlexRay) operating at different source clocks needs to be synchronized to achieve time sensitive functionalities. Currently CAN and Ethernet have their own synchronization mechanisms. In a mixed architecture, challenge is to synchronize nodes on different protocols connected via … The Precision Time Protocol (PTP) is a protocol used to synchronize clocks throughout a computer network. On a local area network, it achieves clock accuracy in the sub-microsecond range, making it suitable for measurement and control systems. PTP is employed to synchronize financial transactions, … See more According to John Eidson, who led the IEEE 1588-2002 standardization effort, "IEEE 1588 is designed to fill a niche not well served by either of the two dominant protocols, NTP and GPS. IEEE 1588 is designed for local … See more The IEEE 1588 standards describe a hierarchical master–slave architecture for clock distribution.
