摘要
为解决PTP协议中传统网络同步时钟方差计算方法无法实时更新和易受外界干扰的问题,提出了一种基于动态指数平滑处理的网络同步时钟方差实时计算方法。试验证明,该算法能够有效抵御外界干扰,及时响应同步时钟稳定性变化和处理网络的异常情况,提高了网络的实时性、同步性和稳定性。
In order to solve the problem that the traditional network synchronization clock variance algorithm in PTP（Precision clock synchronization Protocol） could not update real-time and is venerable to outside noise, a real-time algorithm of network synchronization clock variance is proposed, based on the dynamic exponential smoothing. The experiment shows that it can resist outside noise effectively, respond the stability diversification of synchronization clock and deal with unusual network circumstances. The real-time property, synchronization and stability of network are enhanced.
