The problem in the process of traffic cleaning is that the current DDOS attacks present a mixed attack state with multiple attack methods coexisting. In this case, how to efficiently detect attacks is the main problem currently facing. After consulting numerous data, Huawei's "seven-layer cleaning plan" is found to be very enlightening. The scheme comprehensively analyzes data packets for mixed traffic through seven layers of defense measures such as static filtering, abnormal message filtering, scanning and snooping message filtering, source legitimacy authentication, session-based prevention, feature identification filtering and traffic shaping, so as to detect attack traffic to the greatest extent. The framework of Huawei's "seven-layer cleaning scheme" is shown in Figure 2. After the traffic is cleaned, the attack traffic is discarded, and the normal traffic is injected back into the network through MPLS, GRE tunnel technology, etc.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! Basic implementation:When Tony flew to the entrance of the cave with the bomb in his arms, Stephen's anger replaced sadness, but at the same time he was afraid to let go. He looked at the future and knew Tony would not die. In fact, as he saw, he was extremely angry.王尚书问:玉米丢失后,何人找回来的?如今已经能断定,双方的分歧是从玉米逃出梅县城开始的。I thought this thing was the same as before, Is to rush up and bite people, So we're just shooting with guns, When the distance is close, throw it with a grenade. At the most dangerous time, even mines are thrown out, At that time, the 'round head' anti-infantry mine (still referring to Type 72 anti-infantry mine) had a 'bolt' (i.e. Safety ring) under it. Just pull it out, Throw it out like a grenade, But more powerful than a grenade, As soon as a large area is blown up, But because it is heavier, More than three grenades, Therefore, those with weak throwing ability generally dare not use it like this. Because I'm afraid I can't throw it out of the safe range and blow it up to myself, But fortunately, whatever it is, As long as you want to attack, It must be an attack on the ground, We have a great advantage from a high position. Throwing explosives from high to low can increase the throwing distance, Even if you can't throw it far away, After landing, you can also roll down a little further distance. Therefore, some comrades who throw grenades not far away can also throw mines away from a safe distance to strike the enemy. Then there is the explosive cartridge, The vast majority of people can't throw out three pieces of explosive cartridges in one go like a company commander. And it is too wasteful to throw them all like that, So he threw the explosive cartridges out one by one, When the "big grenade" is used, The reason why I dare to do this and make such "rich" moves is because there are not many others in our positions, that is, grenades, mines and explosive cartridges are plenty of explosives, and many to "tube enough", thanks to these, otherwise in the period of time without artillery support, the Vietnamese army's offensive forces increased several times, and the guns in hand alone could not hold up completely.
