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.神女？楚国一带巫文化由来已久，一听说神女指点，众人都瞪大了眼睛，很是惊奇。滨海市公安局立即成立了专案组，张雷被任命为专案组副组长，与老资格的刑警陆延平搭档。对于张雷来说，侦破这起案件具有双重意义，既是他作为一名刑警必须要完成的职责，又是在为牺牲的好战友和失去了未婚夫的妹妹复仇。但是侦破工作进展得并不顺利，以狡猾擅于躲藏着称的雷老虎在案件发生后就迅速藏匿···毕竟在军事界，特种兵始终有着非凡魅力，引人注目。赵高又问道：去太尉府查一下，驻军彭蠡泽的是谁？出兵去把这下盗匪给我剿灭了。司马二二十二岁出道，他的出道之路，比起现在的陈启丝毫不逊色，当时也是一部小说横扫同辈，然后再一部书横扫前辈，三四部小说便跻身第一流武侠作家。毕竟是姐妹，吕雉也不好多说什么。
