Dual-network synchronous switch and dual-network synchronous switching method

Abstract

The invention discloses a dual-network synchronous switch and a dual-network synchronous switching method, and relates to the technical field of network communication, the dual-network synchronous switch comprises a field programmable gate array (FPGA) and a central processing unit (CPU), the FPGA comprises a high-speed interface processing module, a time frame module, an MAC processing module, a clock synchronization module, a time maintenance module, an FPGA time interaction module and a data exchange module, and the CPU comprises a data processing module, a CPU time interaction module and an Ethernet MAC module. According to the invention, clock information interaction is realized through the FPGA time interaction module and the CPU time interaction module, data exchange is realized through the data exchange module and the data processing module, the Ethernet MAC module encapsulates the received clock information and data, the encapsulated clock information and data can be communicated with other networks, and the communication efficiency is improved. Therefore, clock synchronization and data exchange between double networks are realized.
