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.尤其是看了天启的小说后，杨舟感觉打开了一个新世界的大门，原来武侠是这样子，原来还有修仙这么一说。三十年代初，南方某城市有个贫民区叫猪鸡里，住的都是被有财有势的人压逼得猪狗不如的可怜人。为了达到自己不可告人目的，城中首富庄承和一帮达官显贵要强行拆除猪鸡里，在猪鸡里长大的苦孩子毓儿和庄承的养子留洋博士庄若龙不打不相识，在保护猪鸡里的过程成为了一对欢喜冤家，二人情愫渐生。但是这段感情却注定要经受考验，因为他们是仇家，因为有一连串的大阴谋要陆续登场。在国恨和家仇之间，毓儿和庄若龙发现个人的恩怨已毫无意义，他们放弃了报仇计划，一起连手对付勾结日本人的朱将军等人。一个将计就计的传奇故事，一段至纯至真的浪漫爱情，就这样伴着大时代的风雨飘摇，隆重登场......I just want to know when the display BUG of this bridge can be fixed. ?
