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
[0004] The existing long-distance transmission of heartbeat signals is often achieved by converting heartbeat signals into network signals and transmitting them through routers or switches at all levels. This requires a series of equipment and the cost is very high. At the same time, if the same place The heartbeat signal needs to be transmitted over a long distance, so this method is not suitable, so a network physical link switching heartbeat signal detection module is needed

The invention discloses a detection module of a network physical link for switching a heartbeat signal. The detection module comprises a heartbeat signal receiving module, a heartbeat signal demodulation module, a heartbeat signal modulation module and a heartbeat signal mirror output port, wherein the heartbeat signal receiving module is connected with monitored equipment and the heartbeat signal demodulation module, the heartbeat signal demodulation module is connected with the heartbeat signal modulation module and the heartbeat signal mirror output port, the heartbeat signal demodulation module inputs an output signal into a central processing unit to be processed, and the heartbeat signal mirror output port is connected with the input end of the other heartbeat signal detection module. The detection module can be used for inputting the heartbeat signal of the monitored equipment into the central processing unit to be processed so as to switch a control order of the monitored equipment when the equipment has a fault (like power failure, hardware failure, software crash and linkage interruption), and is applied to protection of flow control equipment and firewall equipment.
Description
technical field [0001] The invention relates to the field of network security and switching, in particular to a heartbeat signal detection module for network physical link switching. 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 fo...
