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.Goo goo goo goo过后又悄悄埋怨他：人家都年轻轻的，就你弄得跟大叔似的。No. 77 Ayu Ting Ting　　…通过以另一个人的身份活下来的女人和真切关注她的男人之间的故事剖析人生真谛。隐藏自己的身份，嫁做财阀世家媳妇的卞智淑（秀爱饰）、愿意无条件去守护心爱女子的崔珉宇（朱智勋饰）、想要揭开智淑的真实身份的人与已经知道所有秘密的人，这四人共同住在同一间宅邸里所发生的明争暗斗、阴谋报复的故事 。
