为此，杨长帆不得不又打出了一个口号——【秀才下海来东番，俸禄百两治苔湾】但凡你有大明的秀才身份确认无误，来苔湾立刻提升为知县以上待遇。So, according to the above thinking, let's summarize what functions each "level" has.当年在上郡，曾经受到méng恬的青睐。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.楚军从心里的呐喊，喊出了他们最渴望的心声。魏铁忍不住道：黎水，好歹咱们是兄弟，你也帮我洗洗，我这铺盖都要臭了。
