摘　　要：针对使用PTP网络授时技术进行复杂网络拓扑时间同步引入的双向延迟测量不对称性以及延迟抖动变化导致网络时间同步精度降低的问题,分析了延迟不对称性及网络延时抖动影响PTP网络时间同步精度的误差原因。通过研究延迟不对称修正、抖动优化等技术,针对性提出了网络时延优化补偿方法,提高了网络时间同步精度。Aiming at the problem of asymmetry of bidirectional delay measurement introduced by using PTP network timing technology for time synchronization of complex network topology and the decrease of network time synchronization accuracy due to the change of delay jitter,we analyze the error reasons of delay asymmetry and network delay jitter affecting the time synchronization accuracy of PTP network,and put forward the optimization method of network delay by studying the delay asymmetry correction,jitter optimization and other techniques,and improve the network time synchronization accuracy.By studying the delay asymmetry correction,jitter optimization and other techniques,the optimized network delay compensation method is proposed to improve the network time synchronization accuracy.
