A system and method for precisely synchronizing clocks in separate nodes (10, 11, 12, 13) on a communication network (15) is provided by adjusting timestamps and related data in network messages. A circuit (10a, 11a, 12a, 13a) will allow a daisy-chain connection of the nodes (10, 11, 12, 13) and will forward time synchronization frames while accounting for delays in a manner that does not use boundary clocks, but does not depart from the IEEE 1588 standard protocol. The delays will be added on the fly to synchronization packets and the IP checksum and frame CRC will be adjusted. Deterministic data delivery and redundant data paths are also provided in a full duplex Ethernet network. |
