Although this kind of attack has appeared for 14 years, its variants can still be seen today. Although technologies that can effectively combat SYN flooding already exist, there is no standard remedy for TCP implementation. You can find different implementations of different solutions to protect the application layer and network layer in today's operating systems and devices. This paper describes this attack in detail and looks forward to and evaluates the anti-SYN flooding methods currently applied to end hosts and network devices.抗日战争时期，日寇入侵我国，广州沦陷。青年学生谭天华随父母前往澳门避难，途中父亲及其他26名抗日志士被日寇渡边大卫及其勾结的“双头鹰”匪帮钱云翔，“龙门帮”沙立标等人杀害，谭天华和谭母被烂仔宏昆救下后逃至澳门，宏昆屡次勒索最后强暴了谭母，谭母含恨自缢而死。　　备将他们秘密接回秦国，恢复他们已经渐被人们遗忘了的秦国太子妃与长公子的身份。Singleton mode: It solves the problem of the number of instantiated objects, such as factories and object pools in abstract factories. Except Singleton, other creative modes solve the coupling relationship brought by new.一切都只是可能，他也没有百分百的把握，这是最后的希望了，也只能尽人事，听天命了。一帮护卫见王爷都下去了，哪敢落后，纷纷脱了外衣、卷起裤腿下水，被冷水一浸，冰得龇牙咧嘴The principle of opening and closing means opening to expansion and closing to modification. When the program needs to be expanded, the original code cannot be modified, but the original code should be expanded to achieve a hot plug effect. Therefore, a summary of one sentence is: in order to make the program scalable, easy to maintain and upgrade. To achieve this effect, we need to use interfaces and abstract classes, etc. We will mention this point in the later specific design.
