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.杨长帆答得痛快，他们若是绕过咱们，咱们便绕过他们。Huang Weiping, born in 1969, was one of the three co-founders of Wake Up and was also the first public welfare person to intervene in hospice care programs in China.
