On the one hand, the core components of the network infrastructure have never changed in the past ten years, which makes some discovered and exploited vulnerabilities and some mature attack tools have a long life cycle and are still valid even today. On the other hand, the rapid development of the application of the Internet seven-layer model has diversified the attack targets of DDoS. From the web to DNS, from the three-layer network to the seven-layer application, from the protocol stack to the application App, the endless new products have also given hackers more opportunities and breakthrough points. Moreover, DDoS protection is a project with unequal technology and cost. Often, the construction cost of a business's DDoS defense system is larger than the cost or benefit of the business itself, which makes many start-up companies or small Internet companies unwilling to make more investment.

From the perspective of service, DDoS protection is essentially a war in which users are the main body and rely on anti-D protection systems to compete with hackers. In the whole process of data confrontation, service providers often have absolute initiative. Users can base on specific rules of anti-D system, such as traffic type, request frequency, packet characteristics, delay interval between normal services, etc. Based on these rules, users can better resist DDoS of the seven-layer class and reduce the resource overhead of the server on the premise of satisfying the normal service itself. The detailed schematic diagram is as follows:
