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.母亲就挑了两个丫头放在我身边。范阳身受重伤不假，可是范紫呢？似乎只是受了些轻伤，若范阳死了，范紫却将消息带回了江东，还是会坏了大事。就算是奢望，朕也要试一试。皇牌公关香广男被誉为城中盛女救星，常以出位手段帮助单身女性客户找到美满姻缘，自己却独善其身，选择短线恋爱，新上班的客户主任盛花蕾，误会广男及其大哥香善男和同事董天骄、毕奋强合称的supersenior组合喜爱夜蒲寻欢，又见广男为追求下属袁萱将她捧为网络歌手，因而不耻广男的所作所为，直斥他是烂滚港男，籍工作亲近女性。身为袁萱的姑姐袁琛同样对广男恨之入骨，经常在自己的专栏恶意抨击广男，但广男对这一切都不以为意，依旧我行我素，直至前女友突然现身，令各人关系出现戏剧性逆转，引爆前所未有的港男剩女大激战《葛雷·奥特曼》是日本圆谷株式会社在1990年把版权卖给澳大利亚而制作的空想特摄系列的电视系列片《奥特曼》中的一部。剧中宇宙飞行员杰克辛德在火星探险，遭遇了宇宙生命体戈迪斯。在那时，银色巨人——葛雷·奥特曼出现，与戈迪斯作战。但是，杰克辛德受伤，葛雷·奥特曼犹豫了一下，戈迪斯趁机分化为细胞，逃往地球。于是，葛雷·奥特曼救下杰克辛德并与之合为一体，回到地球。杰克辛德加入了UMA，与葛雷·奥特曼一起，与被戈迪斯细胞感染而演化出的怪兽做生死对决。
