Abstract

Disclosed are a system time synchronization device and method in a packet transport network, which relate to a packet transport network in optical communications. The system time synchronization device comprises a CPU, a time synchronization module, an FPGA, a 1PPS+TOD time interface, an ingress time stamp module, an egress time stamp module, a first PTP port, and a second PTP port, the FPGA being connected with the CPU through the time synchronization module, the first PTP port being connected with the CPU through the ingress time stamp module, the second PTP port being connected with the CPU through the egress time stamp module, and the FPGA also being connected with the CPU and the 1PPS+TOD time interface, respectively. By way of software-hardware combination, the current invention can effectively and rapidly realize the system time synchronization of nanosecond-level precision between a master station and a slave station in a packet transport network, and realize the high-precision timing of the entire network.
