Remote network control system based on virtual local area network

Abstract

The invention discloses a remote network control system based on a virtual local area network in the technical field of network engineering. The remote network control system comprises a host, an input end of the host is electrically connected with an output end of a local monitoring unit, the host is in two-way electric connection with a PCIE switch, a TCP/IP is in two-way electric connection with a central processor, the central processor is in two-way electric connection with a data transmission unit, the data transmission unit is in two-way electric connection with a remote control unit, data exchange and transmission are carried out by using the PCIE switch and the TCP/IP, data transmission is only allowed between hosts in the same virtual local area network, thereby ensuring the security of data transmission and avoiding network storm, the local control and monitoring of the host are realized by a local control unit, remote control of a host interface, as well as viewing of the host interface are realized by the remote control unit, and in addition, the security coefficient of the system is improved through a background maintenance module.

Description

Technical field [0001] The invention relates to the technical field of network engineering, in particular to a remote network control system based on a virtual local area network. Background technique [0002] In the communication network, the communication equipment needs to be managed, local management and remote management. Among them, remote management is a relatively traditional on-site monitoring mode, combining modern communication technology and information processing technology as a new technology method, especially applied to the field For equipment management with complex environments and low security, such as industrial control and other fields, remote network control systems include remote monitoring. Remote monitoring can be literally divided into two parts: "monitoring" and "control", where "monitoring" is Refers to the main information obtained through the network, and "control" refers to the method of operating remote computer equipment through the network, resta...
