Systems and methods for clock synchronization are disclosed in which a primary node generates special physical laver clock sync symbols from the output of a reference clock and inserts the clock sync symbols within a symbol stream to one or more secondary nodes. Upon receiving a symbol stream, a secondary node can extract the clock sync symbols from the stream to synchronize its local clock with the reference clock of the primary node. In particular, the clock sync symbols can be inserted into the symbol stream at any arbitrary symbol location, e.g., even between consecutive symbols of a symbol encoded data frame. The clock sync symbols can also replace some control symbols in the symbol stream, such as idle or comma symbols. Accordingly, the clock sync symbols can be inserted into a symbol stream at fixed intervals, irregular intervals, or at any arbitrary time for high resolution clock synchronization.

This invention relates to a method for optimizing synchronization accuracy in end-to-end transmission mode clock synchronization systems. First, the master and slave nodes within the clock synchronization system exchange PTP messages in end-to-end transmission mode according to the IEEE 1588 Precision Clock Protocol. The slave node obtains the timestamps and transmission delays recorded in each PTP message. Then, the slave node uses a filtering algorithm to process the forward and reverse transmission delays. Combining this with the clock offset calculation formula in the IEEE 1588 Precision Clock Protocol, the clock offset between the slave node and the master clock is calculated using the timestamps in the PTP messages and the processed transmission delays. Finally, the calculated clock offset is used to adjust the local clock. This invention solves the problem of asymmetric delays during message transmission affecting the clock synchronization accuracy between the master and slave nodes in end-to-end transmission mode clock synchronization systems, improving the time synchronization accuracy between devices in network communication systems and having broad application prospects.
