PTN equipment network time delay monitoring devices based on FPGA

The utility model provides a PTN equipment network time delay monitoring devices based on FPGA, it includes connect a packet control unit based on FPGA between PHY layer and the MAC layer in PTN equipment, packet control unit is unpacked unit, clock and clock multiplier unit, is monitored the data buffering by packet buffer unit, packet packing unit, packet to be formed with processing unit and power, the utility model discloses a connect a packet control unit based on FPGA between PHY layer and the MAC layer in PTN equipment for monitor under the circumstances that does not change original exchange device and system, the cost is reduced has so still realized real-time supervision's function, through the packet buffer unit connect the PTN equipment PHY number of piles according to entry and data export and with clock and doubling of frequency unit connection for control data buffering and processing unit can handle the PTN equipment entry and the data of export, and use local clock as the benchmark, do not rely on the whole network time lock, reduce PTN equipment technical difficulty, handle the time of can improving accuracy nature to the doubling of frequency.
