If an attack is detected, the management center will start a cleaning scheme to pull the mixed traffic of attack traffic and normal traffic through BGP, CDN, etc. Pull the mixed flow to the flow cleaning center for cleaning. 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.大头儿子的爷爷——老头爷爷是个老北京人，做得一手传统京味菜，把大头吃得赞不绝口。大头在幼儿园一番宣传，说自己每天的晚餐如何如何丰富，说得小朋友们馋涎欲滴。超市老板的儿子胖嘟嘟当晚被邀请到大头家，品尝了爷爷做的面条，差点儿连舌头都吞了下去。 但是胖嘟嘟的爸爸妈妈却在烦恼。小区旁边新建了一座大超市，物品全，价格低，而且离小区非常近，把胖嘟嘟家的小区超市挤得够呛，简直是门可罗雀。两口子烦心不已。群众却不乐意了，纷纷怒骂。　　《天空之城》以美丽的西双版纳的热带雨林为背景，讲述了发生在澜沧江边的美丽爱情故事。When attacked by DDoS, the phenomenon is:From the above command class code, we can see that any operation has an execute method to perform the operation. The above code uses traditional object-oriented programming to implement the command mode. The procedural request call of the command mode is encapsulated in the execute method of the command object. Have we found the above writing code a little cumbersome? We can do this using the callback functions in javascript, In object-oriented, The receiver of the command mode is saved as an attribute of the command object, and the command execution operation is agreed to call the command.execute method. However, if we use the callback function, then the receiver is closed in the environment where the callback function is generated, and the execution operation will be simpler. Only the callback function can be executed. Let's look at the following code:小葱接道：不错。
