Abstract :
IEEE1588 precision time protocol (PTP) is a time synchronization protocol that is specially designed for measurement and control field. It is widely used in many fields for high clock synchronization precision, strong stability, low cost etc. In this paper, we study how to make full use of VLAN tag field to improve PTP packets forwarding priority in the second layer switch supporting VLAN, so can reduce jitter and error caused by PTP packets in the network transmission and implement nanosecond precision.
