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.　　《辉煌中国》是由中共中央宣传部、中央电视台联合制作的六集电视纪录片。全片以创新、协调、绿色、开放、共享的新发展理念为脉络，全面反映党的十八大以来中国经济社会发展取得的巨大成就。　　蝙蝠侠和罗宾最终能否化解心结，战胜“急冻人”和“毒藤女”？她身为STARS历代最年轻的总队长，是操纵战略级魔法重金属爆散的USNA最强魔法师——。
