    • A global synchronization method based on a packet switching system includes that: a reference chip is selected; and each chip calibrates its own timer by taking the reference chip as a reference, wherein each chip sends a zero-point pulse or zero-point pulse cell to each high-speed link (serdes) connected with the chip, and feeds back a calibration cell in response to a zero-point pulse or zero-point pulse cell received through each high-speed link. Accordingly, a global synchronization system based on a packet switching system is also disclosed. The disclosure reduces the packet loss rate and increases the accuracy of calibration.
    • 基于分组交换系统的全局同步方法包括:选择参考芯片; 并且每个芯片通过以参考芯片为参考来校准其自己的定时器,其中每个芯片向与芯片连接的每个高速链路(serdes)发送零点脉冲或零点脉冲单元,并且反馈校准 响应于通过每个高速链路接收的零点脉冲或零点脉冲单元。 因此,还公开了一种基于分组交换系统的全球同步系统。 该公开内容降低了丢包率并提高了校准的准确性。
