Network communication system, data transmission method and readable storage medium

Abstract

The invention provides a network communication system, a data transmission method and a readable storage medium, and relates to the technical field of network communication. According to the network communication system provided by the invention, the user terminal is mutually connected with the first communication port of the switch, the plurality of network devices are respectively connected with the second communication port of the switch, and then the plurality of virtual network cards are simulated and created at the user terminal; and each network device independently corresponds to one virtual network card and is located in the same virtual local area network with the virtual network card, so that the network communication system substantially establishes a plurality of virtual local area networks which simultaneously comprise the user terminal and do not interfere with each other, thereby ensuring that the user can access the virtual local area network without modifying the factory IP address of each network device. Data interaction is directly carried out through the user terminal and a plurality of network devices, so that the network communication experience of a user is improved, and the production cost of the network devices is effectively maintained.

Description

technical field [0001] The present application relates to the technical field of network communication, in particular, to a network communication system, a data transmission method and a readable storage medium. Background technique [0002] In the LAN communication process of the network communication protocol stack (Transmission Control Protocol / Internet Protocol, TCP / IP), the data information is transmitted through the message. When the message is transmitted on the network, it is routed based on the protocol (IP, Internet Protocol) address interconnected between the networks. It is required that the IP address of each network device should be unique, so as to avoid problems caused by repeated IP addresses. Network conflict. [0003] However, it is worth noting that most of the network devices currently on the market are general-purpose devices that can be mass-produced and designed by manufacturers out of production cost considerations. Such general-purpose devices need...

Problems solved by technology

[0003] However, it is worth noting that most of the network devices currently on the market are general-purpose devices that can be mass-produced and designed by manufacturers out of production cost considerations. Such general-purpose devices need to be configured with the same IP address when they are manufactured. When users need to exchange data with multiple general-purpose network devices through a terminal device, they often need to modify the unique IP address for each network device separately, which affects the user's network communication experience
