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.女教师劳拉（Joanne Froggatt饰）和学生父亲、外科医生安德鲁（Ioan Gruffudd饰）进行了一次约会，但事后，劳拉称自己遭到了枪见，安德鲁却坚称是两人情投意合，双方对当晚的事各执一词，究竟谁在撒谎？老支书刘茂福即将退休，支部书记的人选成为众村民及乡村干部关注的焦点。经过村干部米粮、曲元宝等人明争暗斗之后，当选的竟然是一位农家妇女—谷雨。众人惊讶之余，也不免为她担忧：“女人不压茬，母鸡不打鸣”，一个女人当村长，行么？谷雨的想法很简单，她就是要解决周边农民卖粮难问题。她虚心接受了“知识分子”夏诗朋的意见，学着“用工业思维考虑农业问题”。她决定办工厂，搞玉米深加工。谷雨以村里一片树林作抵押向银行贷款，办起了柠檬酸厂。但这片树林是鸡鸣甸的“家底儿”，是刘茂福等一些老人的精神家园。伴随着试车失败、产品滞销、事故频发等一系列问题的出现，村民们对谷雨从不理解发展到了行为抵触。婚姻面临崩溃，工厂命悬一线，村民又不理解，谷雨在多重压力下苦苦坚持着。然而，坚强的谷雨还是挺过来了，柠檬酸厂的生产与营销渐渐步入正轨，谷雨又有了进一步发展的大计划……故事开始于上世纪80年代，讲述了一个朴实善良的农村女性，经历种种磨难，将三个孩子拉扯着长大成人的故事。苏春草本来有一份青梅竹马的爱情，却由于对方母亲的反对，只能放弃。嫁给邻村的李二顺后，本想踏踏实实的过日子，帮着婆婆抗起这一大家子，可始终受到嫂子喜凤的排挤,为了翻盖新房，二顺上山采石头，不幸被炸死。喜凤为了争夺财产，和情人牛二远走高飞，设计陷害春草，婆婆一气之下将春草赶出家门。为了偿还父亲苏耗子欠下的赌债，春草带着自己的儿子小浩嫁给了在镇上卖熟食的栓柱。栓柱家除了一个始终对春草抱有敌意的女儿小雪，还有一个疯疯癫癫的父亲,喜凤的儿子大龙，由于已经家破人亡，也被春草接回了家，一家人磕磕绊绊的开始过起了日子。栓柱和疯爷爷的相继离世，春草一个人克服种种磨难，拉扯着三个孩子长大成人，小雪考上了大学，一家人来到了城里,春草艰难创业，屡遇刁难，邂逅初恋情人树林，惨遭牛二、喜凤报复，最终为救小...　　讲述了林府大小姐林若（闫金凤饰），阴差阳错嫁入祁王府，与拥有变身秘密的祁王陆俊逸（王梓霆饰），从针锋相对到敞开心扉，最终相知相恋的爱情故事。
