Anti-attack method, device and equipment based on congestion dissipation

Abstract

Embodiments of the present application provide a congestion dissipation-based attack prevention method, device and equipment, and relate to the technical field of Internet of Things. The method comprises: obtaining a first congestion state of an upstream node and a second congestion state of a downstream node of a cleaning domain; obtaining a congestion wave state based on the first congestion state and the second congestion state; performing peak clipping processing on a first traffic rate of the upstream node when the congestion wave state indicates that the downstream has formed a congestion wave, to obtain a second traffic rate of the upstream node, so that the upstream node outputs service traffic according to the second traffic rate; and cleaning the service traffic output by the upstream node through cleaning nodes in multiple cleaning domains, and outputting the cleaned service traffic to the downstream node. The traffic peak clipping processing in the upstream effectively suppresses the impact of burst traffic on the downstream cleaning nodes, and significantly reduces the access delay of legal users while maintaining a high interception rate.
