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.Pulse output circuit杰西（多米尼克·库珀 Dominic Cooper 饰）曾经是一名黑帮打手，金盆洗手之后，他回到了阔别已久的故乡，继承了父亲的教堂，成为了一名传教士。每一天，杰西都过着浑浑噩噩的生活，丝毫不将自己神圣的职业当做一回事，然而某日，前女友塔里普（鲁丝·内伽 Ruth Negga 饰）和爱尔兰吸血鬼卡西迪（约瑟夫·吉尔甘 Joseph Gilgun 饰）不请自来，彻底搅乱了杰西平静的生活。周青也是松了一口气，张宇正和六公主这事，他本来就不想插手，现在甩给吕洞宾刚好。江城大学有一个“最伟大的推销员”鲁如花，她神出鬼没，能够想尽一切方法推荐各种产品，鲁如花在一次推销中，与在国外长大的富家子弟文初不打不相识。文初在父亲的逼迫下回国的文初仇视一切，更是讨厌“唯利是图、小心眼、市侩”的鲁如花。但在相处中，文初逐渐发现“如花其实不如花”，原来，鲁如花为了生计和学业，帮助患有先天疾病的双胞胎弟弟鲁似玉筹集医药费，才想尽办法去挣钱。冷若冰霜的文初被积极、可爱的如花不断吸引。正当二人感情升温之际，似玉的病情、文初家人的压力向二人袭来。如花的商业才能被盛世集团看中，董事长夜然的特别关怀也让二人的感情出现危机。如花从未向生活低头，而文初亦排除万难走向如花，两人终于走到了一起正午时分，王穷进宫谢恩。　　三鬼找到耕田要出大价钱要耕田把地转包给他，耕田不同意，为此婆姨秀兰和儿子青山与耕田闹起了矛盾。青山以为三鬼花大价钱包地是因为地里头有老年间埋的金元宝，半夜刨了老刘家祖坟，气得刘怀仁来找耕田算账。
