Amplification attack is a special reflection attack. The special feature is that the reflector has the function of amplifying network traffic and is a common technical means in DDoS. Its basic principle is relatively simple. For a C/S service, if the Server-to-Client Response message is larger than the Client-to-Server Request message, the traffic is enlarged. In order to use amplification technology in DDoS, one condition needs to be met, that is, the services provided by Server are based on connectionless protocols such as UDP.

The code for creating the object is encapsulated and the specific factory class is instantiated, thus achieving the purpose of encapsulation and instantiation. Encapsulating the code that creates the object in one place can also achieve the purpose of reuse and is more convenient for later maintenance. This also means that when the customer instantiates the object, he will only rely on the interface and not on the specific implementation. Help us to better achieve interface programming rather than implementation, making the code more flexible to cope with future extensions.
