Network traffic cleaning system and method

Abstract

The invention provides a network traffic cleaning system which comprises a first router, traffic cleaning equipment and a plurality of second routers, wherein a Border Gateway Protocol (BGP) neighbor relation is established between the traffic cleaning equipment and the first router; the traffic cleaning equipment is used for acquiring a network traffic from a first sub-interface, carrying out cleaning according to preset cleaning measurement and feeding back the cleaned traffic to the first router by a second sub-interface; the second routers are connected with the first router; and the second routers have first IP (Internet Protocol) addresses for external access and second IP addresses configured on a loopback interface. The system solves the problem that in the traffic cleaning system, after the traffic is led by a routing layer, load balancing of a line speed of the traffic among a plurality of links cannot be implemented when the traffic is reinjected into a server; and the system breaks through the limitation to performance of the routers, simultaneously provides expansibility of a plurality of equivalent links for network traffic leading and has rapidness, convenience, high efficiency and usability. The invention also provides a network traffic 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 ...

AI Technical Summary

Problems solved by technology

This system solves the problem that in the traffic cleaning system, after the traffic is pulled through the routing layer and injected back 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 Traffic traction provides the scalability of multiple equal-cost links, which is fast, efficient and easy to use
