Precision clock synchronization algorithm based on least squares method

On the premise of thorough studying the clock synchronization mechanism of PTP, this paper carefully analyzed the reasons of the clock offset, introduces frequency compensation algorithm based on least square method to correct the relative clock drift offset, on the basis of the Ethemet accurate clock synchronization platform, through experiment, verify the feasibility of the algorithm. The experimental results show that this algorithm greatly improves the PTP synchronous precision.
