How should we defend against this attack? First of all, as users, we try our best to download APP from regular channels and surf the Internet in a civilized manner, and try our best not to make broilers. Secondly, as a service manufacturer, when the server is attacked by DDoS, we try our best to improve the processing capacity of the server. When the processing capacity of our server is greater than that of the attacker, these attacks are nothing to the server. Finally, under normal circumstances, the processing capacity of our server is generally lower than that of the attacker. In view of this situation, there are currently the following methods: 1. Violent methods, such as setting an access frequency threshold, and rejecting when the number of accesses per IP unit time exceeds this threshold; For a certain service, if the instantaneous request is too large, choose to directly refuse to ensure the normal operation of other services; This method may result in normal users not being able to use it. 2. Verification code. In order to prevent normal users from being injured by exposure methods, at present, service providers will send verification codes to "users" when receiving a large number of requests. If it is a real user, it will input verification codes, but if it is a broiler, it will not. Through this method, the real user and the broiler will be distinguished.当代北京前门大栅栏，瑞蚨祥门前，人流涌动。1867年，山东章丘的一间茶馆里。一个英姿飒爽的青年，巧妙地帮助三兄弟，整分了祖传的一箱元宝。三兄弟千恩万谢，临别时，青年告诉大家：敝姓孟，名继笙，草字洛川。孟洛川之母高夫人，向以孟子的母亲为榜样，眼下，面对着连续气走了三位先生的儿子，她忧心忡忡。北京传来消息，绸布店因为得罪了恭王府的澄贝勒，而惨遭封门。孟洛川临危受命，代表三伯出任瑞蚨祥临时商务主政，前往北京。年少轻狂的他，非但没有为店铺揭封，反而相继受到了岳父的驱逐和澄贝勒的羞辱，北京瑞蚨祥掌柜含恨而死。折羽而归的孟洛川回到家乡，无颜面对自己的过失，一蹶不振。在高夫人的激励下，他重新站了起来。然而三伯的去世，却让他不得不继承了瑞蚨祥商务主政的大印。在认识到自己不足以后，孟洛川拜李士朋为师，其理想中的大商之道，渐渐清晰。学有所成的孟洛川步步为赢，终于得偿所愿，成功使北京分号揭封开门。同时结交了孟觐侯，澄贝勒，龙爷等人。孟洛川的经商之路，开始起程了。此剧该剧讲述了一名小学教师为了拯救被家人虐待的学生，决定成为那个孩子的母亲带着她一同逃走的故事。山芋忙道：小心摔了。/yawn (yawn)没了正当理由，想要明着对付沛公您就不行了。
