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.罗湛约女儿罗想回家，说出了准备再婚的事。罗想惊讶。罗湛向女儿介绍对象白亚莉的情况。白亚莉学小提琴出身，在歌舞团做过乐手，后来不干了，很年轻时丈夫因病去世，有个女儿。罗想心中不悦。罗想家中，罗想把爸爸再婚的事告诉了丈夫严立达，吐露心中疑虑，严立达却感觉无所谓。朱西子回到家。女儿罗想和父亲朱朋石都来了，把罗湛要再婚的消息告诉了朱西子。朱西子反应冷淡。潘良在自己的屋里看书。墙上挂着丈夫罗天安的遗像，是一位老知识分子。罗湛忆起和前妻朱西子的婚姻。罗湛的母亲潘良和朱西子的父亲朱朋石是远房表姐弟，这层亲戚关系使他们很小就相识。但二人性格不合，婚后关系疏远。潘良说他俩很像住在一个宿舍里的室友，谁也不管谁。罗湛说这是他们达成的共识，各干各，各活各，到女儿大学毕业后二人终于分手了。罗想问起白亚莉的经历，白亚莉一一回答。二人正谈着，白亚莉的女儿蔡小先意外回来了。蔡小先见到罗想，两人不快而散。罗湛和白亚莉结婚了。生活的周围掀起波澜。罗想和蔡小先的矛盾不断升级，蔡小先对待爱情的态度和她同时与几个男朋友保持关系的　　正当平安在爱情与报仇间作一抉择之际，方正查出尹明扬之死与警司有关而遭灭口，敖明的安危受到威胁，平安毅然拿起金枪，连番枪战立即爆发……就不能另挑一天吗？《笑傲江湖》电视剧可是就在今天播放。自恋（长濑智也 饰）是一名刑警，有一个刚刚分手的前女友日暮里惠（中岛美嘉 饰）和一幢背负着贷款的为理惠买的豪宅。日暮里惠的嫉妒心和对自恋的盲目崇拜使得自恋变成了一个名符其实的自恋狂，现在自恋狂失恋了，而他的上司冴木优（荒川良良 饰）居然是一个新婚不久的幸福男人，更令自恋震惊的是，讶木的妻子不是别人，正是自己的前女友理惠。莫小妍在体检中被查出罕见的肝脏疾病，通过调查得知林峰与自己相匹配。在莫小妍不断接触下林峰终于接受了她的提议，但由于林峰有些许贫血需要一定的锻炼和营养，莫小妍便给林峰准备了漫长的计划。而俩人也在这段时间暗生情愫。莫小妍生日当天，林峰在地下室看到了一辆车的车牌号备受打击，原来莫小妍就是4年前的肇事司机，而那场车祸导致林峰手背经断裂，无法弹奏，妹妹也因此失明。俩人再无联系。两个月后，妹妹接受了捐献重见光明，而捐献者竟然是莫小妍。林峰看到不能自理的莫小妍，发觉自己其实已经爱上了她，便决定和莫小妍进行肝脏移植手术。Telecommunications
