The target service provider server determines a first SDN controller according to an attack protection request, and issues a first flow rule. The target service provider server directs data flow of a network equipment to a first cleaning center and controls the first cleaning center to identify the attacking or malicious element in the data flow according to the first flow rule. The platform server receives the attacking element in the data flow sent by the target service provider server, and regards the same as malicious traffic. The platform server generates an attack report, and sends the attack report to the botnet service provider server to notify the botnet service provider server to clean or filter out the malicious traffic."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for preventing distributed denial of service attack and related equipment","description":"A method for preventing denial of service attacks which are distributed attacks is applied in a target service provider server, a platform server, and a botnet service provider server.
