Problems solved by technology
[0004] In the above method, when a network attack is detected on any city network core device, the cleaning device will send a traction route to all city network core devices, and each city network core device will forward the upstream traffic to the cleaning device for cleaning. The upstream traffic of the core equipment of the city network where a network attack occurs is prone to problems such as accidental killing of normal traffic, link congestion, and overload of cleaning equipment.

The present application provides a method and device for pulling uplink traffic, which are applied to the management center included in the traffic cleaning system, and the method includes: receiving the alarm information carrying the IP address of the sampling agent and the attacked IP address sent by the detection device, The alarm information is sent after the detection device detects that the city network core device corresponding to the sampling proxy IP address receives the upstream traffic directed at the attacked IP address; according to the corresponding relationship between the sampling proxy IP address and the device label Determine the device label corresponding to the IP address of the sampling agent; generate a pulling route according to the attacked IP address; send the device label and the pulling route to the cleaning device, so that the cleaning device will pull the pulling route The routing and next hop information is sent to the city network core device corresponding to the device label. By applying the embodiment of the present application, it is realized that only the upstream traffic of the core equipment of the city network that has a network attack exists is pulled and cleaned.
Description
technical field [0001] The present application relates to the technical field of network communication, and particularly designs a method and device for pulling uplink traffic. Background technique [0002] With the rapid development of network technology, various network attacks emerge in an endless stream. At present, the more effective means of defending against network attacks is traffic cleaning, such as figure 1 Shown is the architecture diagram of the flow cleaning system, including the management center, cleaning equipment and testing equipment, wherein the testing equipment and cleaning equipment are respectively connected to each provincial network core The communication connection between the equipment and each city network core equipment can be but not limited to Border Gateway Protocol (Border Gateway Protocol, BGP), the management center is respectively connected with the detection equipment and cleaning equipment, and the management center can be but not limi...
