INDUSTRIAL ETHERNET-BASED DATA TRANSMISSION SYSTEM AND METHOD, AND COMMUNICATION DEVICE

摘要

An Industrial Ethernet-based data transmission system, comprising: a transmitting terminal, configured to obtain a data packet, forwardly transmit the data packet to a receiving terminal by means of a first port of the transmitting terminal on the basis of an Ethernet link, and transmit the data packet to the receiving terminal by means of a second port of the transmitting terminal on the basis of a reverse Ethernet link through at least one intermediate terminal; an intermediate terminal, configured to receive the data packet transmitted by the transmitting terminal, and forward the data packet to an adjacent intermediate terminal on the Ethernet link and/or the receiving terminal; and the receiving terminal, configured to receive the data packet transmitted by the transmitting terminal and/or an intermediate terminal adjacent to the receiving terminal, and if the link between the transmitting terminal and the receiving terminal fails, receive the data packet transmitted by the second port of the transmitting terminal on the basis of the reverse Ethernet link through the at least one intermediate terminal.
