The main reason why DDOS attacks are difficult to defend is that there are too many vulnerabilities and attack methods that can be exploited. In the OSI seven-layer network model used in the network data transmission process, basically each layer has protocols that can be exploited by DDOS attacks. According to the different network levels of the protocols used for DDOS attacks, this paper summarizes the currently known DDOS attack types and their defense measures as shown in Table 1-3. For more detailed information on current DDOS attack and defense, please refer to Huawei DDOS attack and defense summary post.　　也是因为儿子——没钱只能就近上一家“胡同小学”，平凡的宋建平终于决定接受林小枫规劝，辞去了国营医院的职务，去了一家外资医院。四院上房，张老太太瞧着一桌子儿孙，笑道：这才热闹。我们的网站就叫‘启明。他们是真的有些被越国骑兵给杀怕了，好不容易获得一个喘息之机，全都倒在地上大口地呼吸生存和自由的气息，一种劫后余生的感觉涌上心头。State machines also have a wide range of uses in game development, especially the logic writing of game AI. The main characters in the game have various states such as walking, attacking, defending, falling and jumping. These states are both interrelated and constrained. For example, if attacked during walking, it will switch from walking state to falling state. In the state of falling, it can neither attack nor defend. Similarly, you cannot switch to the defensive state during the jump, but you can attack. This kind of scenario is very suitable to be described by state machine. The code is as follows:苞谷看着几人斗口，没言语。
