OTN长距离传输时间同步的研究
Research on OTN long distance transmission time synchronization
摘要
Abstract
Based on the current situation of railway time synchronization network,this paper studies the 1588v2 time signal of OTN long distance transmission.Based on the delay of the link and the time difference of the master and slave clock,the paper measures the accuracy of the time transfer,including the OTN time transfer accuracy and the OLP,PTP switching time,obtains the high precision test data.关键词
