Abstract

The embodiment of the invention provides a message transmission method and device, an FPGA and electronic equipment, and the method comprises the steps: obtaining a first message of which the front end is a control information segment and the rear end is a target message segment, wherein the control information segment comprises a data frame indication identifier and a timestamp transmission mode identifier of the target message segment; stripping a control information segment of the first message to obtain the control information segment and a target message segment; determining the type of the target message segment according to the data frame indication identifier in the control information segment; when the type of the target message segment is an event message, generating a timestamp of the target message segment; determining a transmission mode of the target message segment according to the timestamp transmission mode identifier; when the transmission mode of the target message segment is one-step, adding the timestamp of the target message segment to the target message segment; and sending the target message segment comprising the timestamp. Through analysis of the control information segment in the message, stamping of the message timestamp is completed, the implementation and control mode is simple, and system resources can be saved.

Description

technical field [0001] The present application relates to the technical field of communication, in particular to a message transmission method, device, FPGA and electronic equipment. Background technique [0002] The full name of the IEEE 1588 standard is the Precision Clock Synchronization Protocol for Network Measurement and Control Systems, referred to as PTP (PreciseTime Protocol, Precision Time Protocol). It uses both hardware and software to achieve more accurate timing synchronization. In the PTP system, it consists of two parts: PTP-master (master device) and PTP-slave (slave device), and a request-response mechanism is used between them to measure transmission delay. [0003] In the related PTP technology, in the process of sending the PTP message, the timestamp module will decapsulate the packaged PTP message, and analyze the decapsulated PTP message, so as to determine whether to generate the PTP The timestamp of the packet, and repackage the PTP packet. However...
