Improvement of precise time synchronization algorithm based on IEEE1588

In order to satisfy the request for precise clock synchronization in industry Ethernet, this paper has conducted the research to the IEEE1588 high-precision time synchronization algorithm, carried on the elaboration to the principle of algorithm, proposed the corresponding improvement algorithm for asymmetric communication paths and got it verified. The results of test show that the improved method can effectively increased the clock synchronization accuracy under asymmetric communication paths.
