DDOS attacks mainly occur in the network layer. 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.虽然眼下是冬天，可王爷说我们最少也要住到明年春天才回来，我就能看见满山的花儿了……白果语气中透出的欢喜兴奋连毛凡听了都嫉妒。翘儿转头瞪了杨长帆一眼。　　吊儿郎当的将门子弟马八一(夏雨饰)为了一个心爱的姑娘的召唤，出人意外地毅然走进他最头疼的军营，仿佛早已注定：像他这样的人居然会进入部队，而他的人生从踏进部队大门的一刻彻底改变——在熔炉烈火中不甘心成为炉渣，经过十几年的锻烧他终于从一块废铁被百炼成钢！葫芦和板栗浑身一震，但瞬间就反应过来，异口同声地说道：谨遵王命。
