Method and system for realizing two-layer communication between CPE and enterprise router

Abstract

The invention provides a method and a system for realizing two-layer communication between CPE and an enterprise router. According to the invention, setting is carried out at a WAN port of an enterprise router connected with industrial equipment; services are provided for private network addresses in a DMZ port mapping mode; two layers of VE interfaces are bound to a physical Ethernet interface onthe LAN side and a tunnel interface on the WAN side of an enterprise router connected with industrial equipment respectively; the Ethernet message is transparently transmitted through the GRE tunnel,the tunnel from the enterprise router connected with the industrial equipment to the WAN port of the CPE is opened, the LAN port of the CPE is directly connected with the enterprise router connectedwith the industrial equipment, and the two-layer networks on the two sides are opened through the network. According to the method and the system provided by the invention, data exchange between the industrial detection and execution equipment of the terminal and the industrial control host can be realized, real-time and high-precision control response is realized, and a new path is pointed out for the development of a 5G technology and the upgrading of industrial control equipment.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method and a system for realizing Layer 2 communication between a CPE and an enterprise router. Background technique [0002] The fifth generation (5th generation, 5G) network has the characteristics of high speed and low delay. The 5G network is developing in the direction of network diversification, broadband, integration, and intelligence. With the popularization of various smart terminals, mobile data traffic will show explosive growth. 5G technology is helping the transformation of industrial transformation from single-point information technology application to digitization, networking and intelligence. CPE, the English full name is Customer Premise Equipment, and the Chinese name is user terminal equipment. It is a mobile signal access device that receives mobile signals and forwards them with wireless WiFi signals. It converts high-speed 4G or 5G sig...

AI Technical Summary

Problems solved by technology

Enterprise routers can enable industrial equipment to communicate with CPE, the receiving equipment of 5G signals, but the LAN side of CPE is a private network address, and CPE performs dynamic address allocation, while the network communication equipment address of existing industrial equipment is generally a fixed IP address , does not support dynamic IP address allocation, so industrial-grade equipment cannot communicate with CPE
