DDOS attacks mainly occur in the network layer. Its most obvious characteristic is to send a large number of attack packets, consume network bandwidth resources and affect normal users' access. At present, the detection and defense technology for DDOS attacks in the network layer is quite mature, and at the same time, some new attack methods-DDOS attacks in the application layer have emerged. Different from network layer DDOS attacks, application layer DDOS attacks mostly imitate the access behavior of legitimate users and will not generate a large number of attack data packets during data transmission, but they will consume server resources through a large number of database queries and other operations, which is more difficult to detect. According to the different attack modes, DDOS attacks include reflection amplification attacks in addition to ordinary flooding attacks. This type of attack often uses a legitimate server as a reflector, which sends a large number of data packets to the target, thus causing greater harm. At present, DDOS attacks against DNS servers are also common. Attackers often send fake domain names to DNS servers, consuming DNS server resources. At the same time, due to the recursive query mechanism in DNS servers, DDOS attacks against DNS servers have a large impact range.
FlyWeightFactory is responsible for creating and managing meta-units. When a client requests, the factory needs to check whether there are eligible objects in the current object pool. If so, it returns the existing object. If not, it creates a new object. FlyWeight is a superclass. When it comes to shared pools, It is easy to think of JDBC connection pooling in Java, Considering the characteristics of each connection, It is not difficult for us to sum up: Applies to several objects that are shared, They have some common attributes, Take the database connection pool as an example, url, driverClassName, username, password and dbname, these attributes are the same for each connection, so it is suitable to use the meta-sharing mode to process, build a factory class, take the above similar attributes as internal data and the others as external data, and pass them in as parameters when calling methods, thus saving space and reducing the number of instances.

MDT shall establish the following relevant feedback system:
When the server provides some UDP-based services, such as DNS, SMTP, NTP, etc., and finds some requests, in which the Response message is larger than the Request message, the Attacker sends a Request message that forges the source IP, and the source IP forges the IP address of the victim. After receiving the Request message, the server replies the "enlarged" Response message to the victim, thus realizing the amplification of traffic. The principle is roughly as follows:
