到时候鱼死网破，你们连个落脚的地方也没有了。这么久的时间过后，西班牙人也终于有了明确的反应。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.Table 2尽管如此，她还是没能参加比赛。DNS NXDOMAIN Flood attacks are similar to DNS QUERY Flood except that they query real domain names.少女眉头一紧，露出几分凝重之色，良久才悠然说道：很有可能，江东盗匪猖獗，但朝廷都是睁只眼闭着眼，为何此时突然出兵剿匪呢？莫不是因为我们的事，惹怒了赵高，因为连累了尹公子他们？我们突然撤离，让他竹篮打水，必然是恼羞成怒。
