Its most obvious characteristic is to send a large number of attack packets, consume network bandwidth resources and affect normal users' access. At present, the detection and defense technology for DDOS attacks in the network layer is quite mature, and at the same time, some new attack methods-DDOS attacks in the application layer have emerged. Different from network layer DDOS attacks, application layer DDOS attacks mostly imitate the access behavior of legitimate users and will not generate a large number of attack data packets during data transmission, but they will consume server resources through a large number of database queries and other operations, which is more difficult to detect. According to the different attack modes, DDOS attacks include reflection amplification attacks in addition to ordinary flooding attacks. This type of attack often uses a legitimate server as a reflector, which sends a large number of data packets to the target, thus causing greater harm. At present, DDOS attacks against DNS servers are also common. Attackers often send fake domain names to DNS servers, consuming DNS server resources. At the same time, due to the recursive query mechanism in DNS servers, DDOS attacks against DNS servers have a large impact range.　　Mnet《Queendom 2》制作组25日表示：“泰妍自2007年以全球女团少女时代出道后，作为歌谣界One Top Solo艺人，是16年来一直站在顶峰的音乐人。”，“作为后辈女团们想要学习的榜样，期待她超越节目中主持人的角色，发挥多种作用”。A5.1. 3.5 Olfactory examination.I just want to know when the display BUG of this bridge can be fixed. ?
