An Emergency Intelligent Switching System for Network Physical Links

Abstract

The invention discloses an emergency intelligent switching system of a network physical link, comprising a device heartbeat receiving module, a central processing unit, a main memory, a main controller and a sub-control module; one end of the device heartbeat receiving module is connected to a monitored device; the device heartbeat receiving module The other end, the main memory, and the main controller are respectively connected to the central processing unit; the main controller is connected to the sub-control module, and the sub-control module is connected to the monitored equipment. The emergency intelligent switching system using network physical links provided by the present invention is a channel control device, which can be used to bypass the protected device to bypass the node when the protection device fails to ensure that the network is not affected. Provide customers with flexible emergency protection solutions for network equipment, help network platforms realize smooth and real-time transmission of large-flow data, and improve data availability, security, stability and reliability.

Description

technical field [0001] The invention relates to the field of network security and switching, in particular to an emergency intelligent switching system for network physical links. Background technique [0002] With the increasing demand for network broadband in all walks of life, 1000M networks and 1000M communications are gradually expanding in the network market, and firewalls, routers, and server products provided by major companies are also gradually replaced with 1000M links. Therefore, with the expansion of network bandwidth and the increase of the number of users, people pay more and more attention to network security and network stability. [0003] Network security devices are generally used between two or more networks, such as between an internal network and an external network. The application program in the network security device will analyze the network packets passing through it to determine whether there is a threat After processing, the packet will be forwa...

Problems solved by technology

This often requires network administrators to rush to the site immediately for manual operation, which delays the recovery time of the fault, and requires personnel with professional skills to complete the on-site operation. If you use equipment with active and standby functions, only high-end products have The price of equipment with this function is extremely high. For some small and medium-sized customers, it is out of reach, and products from different manufacturers are not compatible. Traditional routing equipment must use equipment from the same manufacturer, and a one-time investment is required to purchase the main equipment. And backup equipment, the initial investment is very large; the existing Bypass can only provide emergency protection for layer 2 network equipment, but it is powerless for layer 3 network equipment, only high-end products have the main and backup functions
