The main reason why DDOS attacks are difficult to defend is that there are too many vulnerabilities and attack methods that can be exploited. In the OSI seven-layer network model used in the network data transmission process, basically each layer has protocols that can be exploited by DDOS attacks. According to the different network levels of the protocols used for DDOS attacks, this paper summarizes the currently known DDOS attack types and their defense measures as shown in Table 1-3. For more detailed information on current DDOS attack and defense, please refer to Huawei DDOS attack and defense summary post.

1989年，大卫·林奇拍了Twin Peaks: Pilot ，讲述FBI探员Dale Cooper 去双峰镇，调查女中学生Laura Palmer被谋杀事件。以大卫·林奇的一贯作风，整出片子到处充满了神秘事件和诡异疑点，而且没有结局可言。这大概引起了观众的不满，或者好奇心。于是，电视台或是创作班底决定以这个为起点，将它发展成一部连续剧。出于神秘的原因，David Lynch不愿担任导演，而是出任执行监制，找了另外的导演来拍摄这部剧集。结果Twin Peaks第1集就已经是一部续集，这就是为什么在第1集时的片头就有“双峰之前”，交代前面的故事。大卫·林奇的《双峰》是美国90年代最为着名的电视剧之一。曾荣获1990年美国电视评论协会大奖，1997年美国金球奖最佳男女主角奖，1991年美国艾美奖8项大奖，1991年美国广播协会最佳电视剧奖，而大卫·林奇也因此登上了《时代》杂志的封面。这部剧集与大卫?林奇的电影作品有很大不同之处，人物众多但个性分明，故事线索分支不多但剧情峰回路转，许多人被Lora的死亡之迷所吸引，也为侦探怪异的侦破方式着迷，虽然到最后也在电视版本中也没交代谜底（虽然林奇宣称他在第二集告诉了观众凶手是谁了），但对人类欲望中产阶级的生活的剖解的相当深刻。而林奇的忠实影迷也不会失望，整部剧集所呈现的特异风格，纠结了怪诞唯美与迷离的气氛，都是大卫?林奇的经典本色。其中Lora还被《Time》誉为电视史上最性感的死尸 。

In the school, there is only an atmosphere of learning. After all, the school is a place of learning. Every student is working hard to achieve higher results. No matter studying or working, there is competition. In the competition, we must constantly learn from other people's advanced places and how others are to be human, so as to improve our potential. I remember the teacher said before that the university is a small society, but I always feel that the innocence and sincerity are indispensable in the campus. Although it is a university, the students still continue to be students. Contact those senior students who have just graduated, they always team me and say that they should cherish their time at school. In this practice, I feel very deeply that in school, there are a lot of theoretical studies, and they are multi-faceted, almost all-encompassing. However, in actual work, one may encounter the situation that one has not learned from books, or that one may not use the knowledge from books at all.

"With the experience of the above two times, I realized it wasn't that simple, For example, I observed these dogs at that time. But it is definitely not a dog's strange thing. Apart from being large in quantity and fast in speed, In addition to a very strong sense of attack, There is still some tactical nature, In the words of my teachers at the military academy, 'Tactical awareness is a further sublimation of basic organization', I feel it is most appropriate to use this word on these strange things. They know that they are surprised and flank while attacking the front. I also assumed that they were trained by the Vietnamese army, but I didn't think of a clue and didn't continue to think about it.
