Embodiment Construction

[0023] The present invention is further illustrated below by means of examples, but the present invention is not limited to the scope of the examples.

[0024] Such as figure 1 As shown, the switch-based firewall automatic bypass system of the present invention includes a network deployment module 1 , a network configuration module 2 , a firewall monitoring module 3 , a firewall automatic bypass module 4 , a firewall recovery module 5 and an information notification module 6 .

[0025] Wherein, the network deployment module 1 is used to connect the firewall between two switches, and deploy a bypass physical line, and the bypass physical line is used to directly connect the two switches; the network configuration module 2 Then configure the network spanning tree protocol, set the priority of the network interface of the bypass physical line (i.e. the network direct connection interface of the switch) to be high; transmit the routing information of the firewall to the two switch...

Abstract

The invention discloses a method and a system for firewall automatic bypass based on switches. The method comprises steps: S1, the firewall is connected between two switches, and a bypass physical line is deployed for directly connecting the two switches; S2, a network spanning tree protocol is configured, the network interface of the bypass physical line is set to have a high priority, the routing information of the firewall is transmitted to the two switches, the routing priority is set to be high, and the network interface state of the bypass physical line is set to be down; S3, the network state of the firewall is monitored at each time interval, and after abnormal network states appear at several times continuously, S4 is executed; and S4, the network interface state of the bypass physical line is set to be up, and the flow between the two switches is operated through the bypass physical line. The bypass function is automatically executed in the case when fault happens to the firewall, and the time for trouble shooting and change is saved.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a method and system for automatic bypass of a switch-based firewall. Background technique [0002] A firewall is an important tool used in the field of network security to block illegal requests to websites. It is usually deployed in series in network links. If a fault occurs or the operation is changed, it will cause website access problems. There are many brands and models of firewalls that do not have a built-in bypass (bypass function) module. When problems such as power failure, hardware failure, or operating system failure occur, engineers need to go to the computer room to solve the failure on site, which will waste a lot of time and cannot meet the fast Request to resume website business. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a switch-based automatic firewall bypass method and system in ord...
