Today, distributed attacks are really feasible because criminals have thousands of hosts for him to carry out denial of service (DoS) attacks. Since these large numbers of hosts can continuously increase or decrease and can change their IP addresses and their connections, it is still a challenge to prevent such attacks.At present, what methods do we take to solve the attack? The first method shortens the waiting time and deletes the illegal request data packets waiting in the waiting queue as soon as possible. The second method is that the first handshake message is not put into the waiting queue. We return a 32-bit unsigned integer to the client as the Seq of the second handshake. The integer is obtained by adding a serial number of the server to the parameters requested by the user (including the requested address, port, etc.). If it is a normal user, it adds 1 as ACK after receiving this integer and returns it to the server. After receiving the data, the server subtracts 1 from this ACK and then performs inverse operation to obtain various parameters. Finally, the data sent out are compared. If they are completely consistent, it means that it is an effective response and stored in the corresponding data structure, otherwise it is not. Through this method, illegal requests cannot occupy system resources.讲述了杨戬（李东学饰）闯风雷塔战三霄恶灵诛邪神,开天眼封神的故事。他与采莲女梦月（付梦妮饰）,镇长之子余浪（扈帷饰）组成诛神天团,合力破除九曲黄河阵,守护一方百姓。在闯关破阵中,杨戬化火煞开天眼,实现了从凡人到封神英雄的蜕变,触发其开天眼的最强助攻,是本命为业火红莲的梦月。郑氏和刘氏在隔壁听见这边笑，走过来问：什么事笑成这样？绿菠赶忙就把刚才的事告诉了大伯母。十年前，天远少掌柜江海生猛烈追求庆余大小姐程雪，为吞并庆余茶庄。老掌柜冯燕为保全祖业，临终前逼义子王荣华抛下怀有身孕的结发妻子入赘程家，认下程雪腹中海生的血脉，立毒誓终身捍卫庆余茶庄。上辈恩怨波澜未平，荣华的亲生儿子王志诚（阿诚）和程雪之子程大宝同时降生。阿诚从小便忍受饥贫和侮辱。为改变儿子命运，身患绝症的荣华与程雪做出交易，让阿诚进入庆余茶庄，开始了饱受磨难的学徒生涯。二十年后，少年一代长大成人。程大宝羸弱荒唐难担庆余重任，阿诚继承父志忠心辅佐程雪，却屡受排挤。阿诚与邵庆玲相互爱慕，但由于对庆余的责任及大宝的纠缠。阿诚被赶出庆余，茶庄因大宝面临灭顶之灾。程雪独力难支，请阿诚回来帮忙，阿诚重新出发，迎接未来的挑战。On July 23, ZTE's first 5G mobile phone also began to be pre-sold.
