Surname is a sign and symbol that indicates a person's family and blood relationship. The descendants of the same ancestor are called clans. Surnames originated from the name of the tribe or the name of the tribal leader. Its function is mainly to distinguish the descendants of different clans in the tribe and to facilitate intermarriage between different clans. Therefore, the emergence of surnames marks the change from group marriage to blood marriage and is an important milestone in the progress of human civilization.

《刑警队长》筹备历时3年，是一部经精心雕琢和细致打磨而成的高质感大剧。顾瑛亲手破获的大量现实案件在剧中被真实还原。值得一提的是，在案件的选择上，制作团队同样煞费苦心，力求在折射出人性复杂和黑暗的同时展现刑警丰富多彩因地制宜的破案手段，或布局引蛇出洞，或锲而不舍通过笔迹和画像追凶，甚至案中有案，抽丝剥茧下真凶依旧扑朔迷离。

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.
