Abstract: Aiming at the lack of low time accuracy on Cristian algorithm and Berkeley algorithm, this paper presents a clock synchronization algorithm. It gets more accurate drift rate by calculating more accurate delay, and determines a more precise synchronization cycle and synchronization mode by using the redundant synchronization strategy. Experimental result shows that compared with Cristian algorithm, the algorithm proposed has higher time accuracy.

摘要： 针对Cristian算法和Berkeley算法同步时间精度不高的缺陷，提出一种基于反射内存的网络时钟同步算法。该算法通过计算出准确的延迟得到较精确的漂移率，并采用渐入渐出的同步冗余策略来确定较精确的同步周期和同步方式。实验测试结果证明，与Cristian算法相比，该算法的时间精度更高。
