Problems solved by technology

Point-to-point transmission through the port does not perform any splitting and splicing of data packets, so the transmission speed is fast and suitable for real-time transmission applications. The disadvantage is that there is no sending and receiving confirmation mechanism, and the correctness of the data received by the receiver cannot be guaranteed.

Embodiment Construction

[0036] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0037] This application is a self-defined protocol based on the UDP / IP transmission protocol. The data frame and command frame structure are designed separately, and data verification and retransmission mechanisms are added to ensure the transmission rate and quality. This protocol can be used for FPGA-based Ethernet interfaces such as figure 1 As shown, the transport layer network layer data module completes the data processing according to the transport layer / network layer protocol, and the custom protocol designed by this application is located in the application layer data processing module, which integrates the data processed by the transport network layer ...

Abstract

The invention discloses an Ethernet data transmission method by adopting a custom protocol. The Ethernet data transmission method comprises the following steps that: S101, a sender sends a monitoringstarting command and a transmission starting command; S102, the sender starts monitoring and data transmission after receiving the corresponding return commands sent by the receiver; S103, after the transmission is finished, the sender sends a monitoring closing command and a transmission stopping command; and S104, the sender stops monitoring and data transmission after receiving the corresponding return commands sent by the receiver respectively. Based on a UDP protocol, a monitoring and command transmission mechanism and a corresponding command return mechanism are adopted, so that the transmission rate is ensured, and the problem of unreliable transmission caused by no connection of the UDP protocol is solved.

Description

technical field [0001] The invention relates to the technical field of Ethernet connection, in particular to an Ethernet data transmission method using a self-defined protocol. Background technique [0002] Ethernet (Ethernet) is a set of computer network technologies widely used in local area network (LAN), metropolitan area network (MAN) and wide area network (WAN). It was first introduced commercially in 1980 and was standardized by IEEE 802.3 in 1983, and has since been improved to support higher bit rates and longer link distances. [0003] The TCP / IP network model is simplified from the OSI seven-layer model, which consists of data link layer, network layer, transport layer and application layer from bottom to top. Ethernet data transmission is essentially a process of filling data frames at each layer, and all TCP, UDP and other data are transmitted in IP datagrams. The data link layer is responsible for encapsulating and unpacking IP packets, the network layer is r...
