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.郭寒一直在经营着自己的杂志，小说都是连载在杂志上，或者直接出版，很少涉足网络这一块，所以谁也没有想到，这次他会加盟星海。作为tvN5月期待作的《Abyss》确定了朴宝英、安孝燮、李成宰、李时言、韩素希、权秀贤的演员阵容。杨长帆不住自责：是我的错……都是我的错……受苦了……翘儿偎在杨长帆怀中哭道：若不是必归必远，我和两位妹妹怕是真见不到相公了。《金山上的树叶》是一部现实题材的网络电影，该片以黄杜村党员向湖南省古丈县、四川省青川县以及贵州省普安县和沿河土家族自治县捐献“白叶一号”扶贫苗为背景创作，讲述黄杜村人在绿水青山就是金山银山理念指导下实现自我富裕的同时，不忘为党分忧，先富带动后富实现共同富裕的生动故事。更近一些，戚继光更慌了。这就好比喂鸡，你天天早上喂，那鸡见了你就围上来了。
