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 with 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 tr...
