The SYN-Flood attack is currently the most common DDoS attack on the network, It is also the most classic denial of service attack. It takes advantage of a defect in the implementation of TCP protocol. By sending a large number of attack messages with forged source addresses to the ports where the network service is located, it may cause the half-open connection queue in the target server to be full, thus preventing other legitimate users from accessing. This kind of attack was discovered as early as 1996, but it still shows great vitality. Many operating systems, even firewalls and routers, cannot effectively defend against this kind of attack, and it is very difficult to trace it because it can easily forge the source address. Its packet characteristics are usually that the source sends a large number of SYN packets and lacks the last handshake ACK reply of the three handshakes.

Due to the large number of test data, the landlord only selects a rocket minimum value (Figure 1), a poison arrow minimum value (Figure 2) and a poison arrow median value (Figure 3) for explanation. Most of the rocket damage tested by the landlord was in the early 15W 's, while most of the poison arrow damage was about 14W' s. 15/14-1 = 7.14%. At this addition (30% +40% +100% +20% * 2) = 210%. 210% * 7.14% is about 15%. This is equivalent to flame being born 15% higher than virulence. Since it is impossible to know how much or not this ratio fluctuates with skills, the accurate value cannot be estimated. For the bow, the final poison damage is 230% (20% more for the auxiliary weapon), so even if it does not fluctuate with the skill, it will get a highly toxic damage entry slightly higher than 15%. The value of 15% can be used as a reference.

User class unified interface, User1 and User2 are different objects respectively, and they are related. If the mediator mode is not adopted, the two need to hold references to each other, so the coupling degree between the two is very high. In order to decouple, the Mediator class is introduced to provide unified interface, and MyMediator is its implementation class, which holds instances of User1 and User2 to control User1 and User2. In this way, User1 and User2 objects are independent of each other. They only need to maintain a good relationship with the Mediator, and the rest is maintained by the MyMediator class!
