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.《五子说》故事梗概由蔡志忠漫画改编而成，全篇分为五个部分《庄子说》、《老子说》、《孟子说》、《孔子说》、《孙子说》。采用夸张变形等不写实的笔法，将五人博大精深的哲学道理、处事原则、思想观念等复杂的内容，用诙谐有趣的绘画技法，简单易懂的说理方法，以讲故事为载体，通过很多有趣的小故事，比如人物故事、动物故事、山水花鸟故事、以及新编故事，灵活的表达出来。(a) beyond the scope of qualification license to engage in social fire technical service activities;　　赌博让人迷失本性，叠码仔与赌徒周旋，也等于与魔鬼打交道，一时假仁假义，一时恩断情绝，赌至终局，谁能寻回本性，谁能鸿运当头？把香荽也叫过来，母女三个说话。(4) Purposeful exercises need to go out of the comfort zone.
