  Abstract

In this paper, we describe the design and implementation of IEEE 802.1AS high-precision time synchronization capable MAC for TSN(Time-Sensitive Network), which is being actively studied as a next generation network technology for controlling and monitoring industrial IoT devices. The proposed MAC supporting IEEE 802.1AS Time Synchronization is composed of Ethernet MAC and Time-of-Day module based on ALTERA SoC FPGA and is implemented to control corresponding hardware block with the ARM processor embedded in SoC FPGA. In addition, we implemented IEEE 802.1AS time synchronization capable MAC device driver on Linux OS (ubuntu 16.04 LTS) to evaluate time synchronization accuracy performance using LinuxPTP, an open source program for PTP(Precision Time Protocol). The experiment results show that the time synchronization offset of the proposed MAC is rms 125ns at range from 1982ns to -2991ns.
