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...
