Industry 4.0 proposed by Germany has three major themes: first, intelligent factories, focusing on intelligent production systems and processes, and the realization of networked distributed production facilities; The second is intelligent production, which mainly involves the production logistics management of the whole enterprise, human-computer interaction and the application of 3D technology in the industrial production process. The third is intelligent logistics, which integrates logistics resources mainly through the Internet, the Internet of Things and the Internet of Services to give full play to the efficiency of existing logistics resources.罗利带着海外新鲜的探险经历在女王面前出现，令女王多年尘封的心有了悸动。然而，女王的爱情，注定了要屈服于国家的利益。Temperature (℃)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.）……(未完待续。放心，《白发魔女传》的结局绝对是很经典、可以让人回味无穷的结局，不会让你们失望的。朝廷上不对付的人多的很，可少有人会撕破脸，再大的恨都放心里。
