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.余者要么是七扯八拉的亲戚，要么是拐弯抹角的朋友。游一桥（郑少秋 饰）是桌球界当之无愧的天王，然而，某一日，他却突然宣布隐退，然而，游一桥内心里对桌球的热情却没有半点减少。父亲的决定令同样热爱桌球的女儿游加勒（周丽淇 饰）深感不解。一天，游一桥遇见了名为靳子谦（邓健泓 饰）的男子，发现了他身上潜藏的卓越天赋，遂收他为徒，游加勒则顺水推舟的成为了靳子谦的师姐。毕业在即，实习生苏冉冉为了能够顺利告白，努力加入爱慕对象徐启恒所在的游戏公司，却在入职的第一天意外和公司的创始人——庄叙发生了冲突。在测评游戏之际，两人意外灵魂互换。面对苏冉冉的告白，庄叙抱着作弄人的心态答应，而此事让只把苏冉冉当妹妹的徐启恒很是苦恼，为了把伤害降到最低，两人不得不将错就错。可在与苏冉冉的朝夕相处之中，两人都与这个女生发生了奇妙的化学反应。与此同时，苏冉冉也逐渐察觉到了异样，真相揭露之余，三人的感情将何去何从......聪明美丽的吴依凡（周显欣饰）和活泼可爱的妹妹吴依人（姚笛饰），与知书达理的母亲黄慧英（徐幸饰）相依为命，过着清贫舒心的日子。不料天意弄人，噩梦打破了他们平静的生活。妹妹吴依人肾功能衰竭急需换肾，20万的手术费对吴家来说简直是一个天文数字。吴依凡一筹莫展地来到男友左建宏（迟帅饰）上班的家具城，惊愕地发现竟然有人花40万购一只梳妆台，只为博老婆一笑！她惊呆了。在商场一掷千金的是佳诚集团的老板陆文骏，他的事业顺风顺水，家庭生活却磕磕碰碰。性格古怪的父亲（周琦饰）和骄傲自负的妻子罗碧纹（王姬饰）无休无止的争吵让他身心疲惫，夫妻间的隔阂越来越大，感情出现了危机。一次争吵中，陆父受伤，去医院治疗时巧遇吴依凡一家。吴依凡在得知陆文骏不惜重金为父亲物色老伴后，一个巨大的计划在她脑海中形成：也许这个机会可以拯救妹妹，也能改变自己的命运！这一次，皇帝没有任何犹豫。
