Abstract

The embodiment of the invention provides a method for verifying the validity of a flow strategy, and the method is used in any network equipment. The method comprises the steps: recognizing a target address, which is in inclusive or included relation with the target address of changed unicast routing, in the target address corresponding to each flow strategy stored locally when any unicast routing changes; determining the flow strategies corresponding to the recognized target addresses, and carrying out the inspection of the validity of each flow strategy. According to the embodiment of the invention, the method can improve the inspection efficiency of the validity of the flow strategies, saves the system resources, and guarantees the normal operation of businesses.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method and device for checking the legality of traffic policies. Background technique [0002] The flow policy (Flow Specification) can be used to accurately match attack traffic (source address, destination address, port, source port, destination port, protocol type, etc.), and has multiple options for attack traffic: discard, rate limit, flow Redirection, etc., is an effective method to defend against denial of service (Denial of service, DoS) and distributed denial of service (Distributed Denial of service, DDoS) attacks. [0003] With the multi-protocol expansion capability of BGP (Border Gateway Protocol, Border Gateway Protocol), traffic policies can be easily distributed to devices configured with BGP protocol to limit the traffic that initiates DoS / DDoS attacks. [0004] When a network device uses a traffic policy to control traffic matching for a specific desti...
