Network traffic cleaning system and method

Abstract

The present invention proposes a network traffic cleaning system, including: a first router; a traffic cleaning device establishes a Border Gateway Protocol (BGP) neighbor with the first router, and the traffic cleaning device obtains network traffic from the first sub-interface, and performs cleaning measurement according to a preset Cleaning, and feeding back the cleaned traffic to the first router through the second sub-interface; multiple second routers are connected to the first router, and multiple second routers have the first IP address for external access, and are configured on the loopback interface of the second IP address. This system solves the problem that in the traffic cleaning system, after the traffic is pulled through the routing layer and re-injected to the server, the traffic cannot achieve line-speed load balancing among multiple links, breaking through the limitations of router performance, and at the same time providing Network traffic traction provides the scalability of multiple equivalent links, and is fast, efficient and easy to use. The invention also proposes a network flow cleaning method.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a network traffic cleaning system and method. Background technique [0002] In the prior art, in the network traffic cleaning system, the traffic cleaning device obtains network traffic from the first router, performs cleaning after predicted cleaning measurement, and injects the cleaned network traffic back into the first router, wherein the first router is at Configure policy routing in the inbound direction of the interface interconnected with the traffic cleaning device. When the first IP address is matched, that is, incoming network traffic, the next hop of the policy routing of the first router points to the second IP address, because the second IP address is not the first router. Therefore, it is necessary to carry out route recursive query, forward policy routing to the second router and the third router, and finally inject the network traffic back to the first ...
