Editor's comment: The BMW 3 Series has a total of six generations of models since its development. The good reputation and mature design of the previous generation of models make the new BMW 3 Series not need to innovate the overall chassis structure, which is also the accumulated result of the BMW 3 Series over the past 40 years. The overall structure of the new BMW 3-Series chassis makes it worthy of the title of the same control benchmark. Compared with this, what makes people feel more valuable is the emphasis on chassis details of the new BMW 3-Series, and it is this spirit of pursuing perfection that enables the BMW brand to have a strong foothold for a hundred years.《大敦煌》采用宋代、清末和民国三个历史阶段的创作形式，以一部金字大藏经的命运为贯穿，反映了千年敦煌的形成、发展、辉煌、衰败、重生的过程。时隔2年回到了故乡和歌山市日都岛。出了木屋，就听前面喊杀声一片。好了。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.
