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.-> This function-> and recycles event objects that do not call persist to the event pool.宫本是个职场菜鸟，在恋爱和工作上都十分笨拙，一直烦恼著自己在社会上生存的意义。直到某日，和靖子一见钟情后，他的人生终于露出一线曙光，稳定的日子过没多久，却突然发生了一件大事，彻底的改变了他们，让靖子和宫本的关系降到了冰点，宫本要如何做才能巩固这份得来不易的爱情呢？此剧讲述于斗争中遭受不公正对待被逼到悬崖边的女人，与抛弃挽救自己家人的男人，七年后再次相遇并从地狱里回来开始对伤害过自己的人开始报复。唱片制作人张哲凯(刘以豪)和王牌作词人宋媛媛(陈意涵)相依为命，两人自幼身世坎坷只有彼此为伴，他们是亲人、是朋友，也彷佛是命中注定的另一半。父亲罹患遗传重症而被母亲抛弃的哲凯，深怕自己随时会发病不久人世，始终没有跨出友谊的界线对媛媛展露爱意。眼见哲凯的病情加重，他暗自决定用剩余的生命完成他们之间的终曲，再为媛媛找个可以托付一生的好男人。这时，事业有 成温柔体贴的医生(张书豪)适时的出现让他成为照顾媛媛的最佳人选，二人按部就班发展着关系。一切看似都在哲凯的计划下进行。然而，故事远比这里所写更要悲伤......八十年代，歌女朱莎娇(米雪饰)独自带着孪生女儿在流浮山生活，可惜一对女儿长大后却为爱情决裂。莎华离家出走，莎莎难产逝世，莎娇从此肩负照顾外孙女君好的重任，以及收养了哑巴小男孩文初。时光荏苒，君好(何依婷饰)生父祝展辉(海俊杰饰)的出现，令莎娇、莎华(姚嘉妮饰)和君好这三代关系，再次陷入爱恨纠缠之中。文初(胡鸿钧饰)、君好与年青有为的司徒礼信(罗天宇饰)因缘分结为好友，渐渐让兄妹间泛起超乎亲情之爱，更牵进三角虐恋，无法抉择，唯有以牺牲和无私奉献，成就挚爱的幸福...Solidago canadensis
