The invention discloses data frame concurrent service generating equipment based on a VL. The data frame concurrent service generating equipment comprises a frame payload data register, an FPGA module and an MAC layer interface circuit. The FPGA module comprises control information registers, a frame number hardware concurrent processing circuit, an SN generating circuit, a frame interval concurrent processing module, a frame interval control module and a frame convergence module. The FPGA module reads frame control information and frame payload data at first, then frame numbers generated by the SN generating circuit are added to data frame ends to form complete data frames, the complete data frames are sent to the frame convergence module through the frame interval control module for data frame rearrangement, and ultimately the data frames are sent to the MAC layer interface circuit for data frame physical sending. Concurrent operation control over hardware can be achieved through VL data frames within the range of 2048, and each VL data frame is provided with one exclusive control information register.
