Problems solved by technology

[0011] It can be seen from the above scheme that the first abnormal flow control system needs to clean all the traffic of the attacked device, which will cause the normal traffic in the attacked device to occupy the cleaning resources of the cleaning device and increase the pressure on the cleaning resources of the cleaning device. On the other hand, since the abnormal traffic control system identifies all the traffic of the attacked device according to the destination address of the traffic, the destination address of the traffic will not change after cleaning, so the cleaning devices at all levels through which the abnormal traffic flows will clean the abnormal traffic. This can cause problems with rewashing or even multiple washes
[0012] In the second abnormal traffic control system, all traffic must pass through detection equipment and cleaning equipment, which will cause delays to normal traffic and affect service quality

Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0030] image 3 It is a structural diagram of the first flow control system provided by the present invention.

[0031] Such as image 3 As shown, the first traffic control system provided by the present invention includes a traffic marking device 301 , a distribution router 302 and a cleaning device 303 .

[0032] The traffic marking device 301 identifies abnormal traffic from current traffic, and identifies the abnormal traffic.

[0033] The distribution router 302 routes the identified abnormal traffic to the cleaning device 303 .

[0034] The cleaning device 303 cleans the abnormal flow.

[0035] Usually, after cleaning the abnormal traffic, the cleaning device 303 deletes the traffic mark contained in the cleaned traffic, and then returns it to...

Abstract

The invention provides a flow control system and method. The system provided by the invention comprises flow marking equipment, a shunting router and cleaning equipment, wherein the flow marking equipment identifies abnormal flow from the current flow and marks the abnormal flow; the shunting router routes the marked abnormal flow to the cleaning equipment; and the cleaning equipment cleans the abnormal flow. According to the invention, the abnormal flow can be cleaned, and the resource pressure of the cleaning equipment can be reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a flow control system and method. Background technique [0002] In a communication system, in addition to normal business traffic, there may also be abnormal traffic such as malicious attacks. How to control abnormal traffic is a common problem faced by various communication systems. [0003] Currently, there are two main solutions for abnormal flow control. For details, see figure 1 and 2 . [0004] figure 1 It is the structural diagram of the first abnormal flow control system at present. [0005] Such as figure 1 As shown, the first abnormal flow control system includes a detection device (DFI or DPI) 101 , a router 102 and a cleaning device 103 . [0006] Among them, the detection device is deployed outside the traffic line in a bypass, finds abnormal traffic through optical splitting or mirroring, and then notifies the cleaning device to pull all the tra...
