Emergency intelligent switching system of host/backup mode network physical link

Abstract

The invention discloses an emergency intelligent switching system of a host / backup mode network physical link. The emergency intelligent switching system comprises a server, protected equipment, standby equipment, a client, a first sub control module and a second sub control module, wherein the server is connected with the input end of the first sub control module; the output end of the first sub control module is respectively connected with input ends of the protected equipment and the standby equipment; output ends of the protected equipment and the standby equipment are connected with the input end of the second sub control module; the output end of the second sub control module is connected with the client; the protected equipment is connected with a switch system through a heartbeat control line. The switching system provided by the invention is suitable for switching the protected equipment to the standby equipment to ensure that a network is not influenced when the protected equipment fails. The switching system can be used for providing host / standby protection to different routing equipment. The switching system provides a flexible network equipment emergency protection scheme for a customer to help a network platform realize smooth and real-time transmission of a massive dataflow, thereby improving data availability, safety, 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 in master / standby mode. 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, t...

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
