Example Embodiment

[0021] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] The method provided by the present invention mainly includes: adopting independent power supply for the bypass device, the bypass device monitors the state of the IPS device through the control interface, and when the IPS device is detected to be faulty or overloaded, the bypass device Switch to the bypass state; when it is monitored that the IPS device returns to normal, the bypass device is switched to the access link state.

[0023] In the above method, the power supply to the bypass device and the power supply to the IPS device are independent. The power supply capability of the bypass device can be designed according to the specific power consumption requirements of the bypass device. For example, the larger the port scale supported by ...

Abstract

The invention provides a method and a system for bypass changeover, and a bypass device. Provided with independent power supply, the bypass device monitors the state of an intrusion prevention system (IPS) system by a control port; when the breakdown or the overload of the IPS device is detected, the bypass device is switched to a bypass state. As the bypass changeover of the bypass device of the invention does not rely on the IPS to supply power to the bypass device, but adopts the way of monitoring the state of the IPS system, and the ability of the independent power supply of the bypass device can be independently designed according to the scale of the port self, the load caused by the bypass device to the power supply and the power of the IPS device is prevented and the scale of the port of the bypass device can not be limited by the ability of the IPS power supply.

Description

technical field [0001] The invention relates to network communication technology, in particular to a bypass switching method, system and bypass equipment. Background technique [0002] With the continuous development of network technology and the continuous expansion of the scale of the Internet, network security issues have attracted increasing attention. In addition to completing data transmission, links in the network also need to perform some special monitoring and filtering of data to ensure network security. Security, intrusion prevention system (IPS, Intrusion Prevention System) equipment is a security protection equipment that performs such a function, and because of its flexible networking and powerful functions, it is increasingly used on a large scale. [0003] Since the IPS device is serially connected to the network link, if the IPS device itself is overloaded or fails, the network link where the IPS device is located will suffer from data loss or service interr...
