Abstract

本申请涉及通信技术领域，公开了一种打戳处理方法及装置，用以提高打戳处理的准确性，进而保证延时测量的准确性。该方法为：网络节点对以太端口接收到的多个PTP报文分别打入第一时戳；其中，所述以太端口具有多个lane，所述多个PTP报文为所述网络节点通过所述多个lane接收的；所述网络节点在所述多个PTP报文跨过时钟域后，将所述多个PTP报文中分别打入第一时戳的第一时戳值，更新为所述多个lane中目标lane接收的目标PTP报文对应的目标时戳值；所述网络节点根据所述目标时戳值与所述多个PTP报文的发送时戳的时戳值的差值，确定所述网络节点与发送所述多个PTP报文的网络节点间的延时。
