So how does the system detect SYN attacks?

The following procedure is to use the state mode to improve the light. When it comes to encapsulation, the behavior of the encapsulated object is generally preferred over the state of the object. But the opposite is true in state mode, The key to the state mode is to encapsulate each state of the thing into a separate class, and the behaviors related to this state are encapsulated inside this class, so when button is pressed, only the request needs to be delegated to the current state object in the context, and the state object will be responsible for rendering its own behaviors. At the same time, the state switching rules can be distributed in the state classes in advance, thus effectively eliminating a large number of conditional branch statements that originally existed.
