Using input source filtering, ISP refuses to route a packet whose source IP address does not belong to its source subnet further. Input source filtering can effectively prevent SYN flooding attacks disguised as IP. However, this method is useless at present because it is difficult to deploy on a large scale. Moreover, input source filtering cannot resist distributed attacks.When the SYN gateway receives the SYN packet from the client, it directly forwards it to the server. After receiving the SYN/ACK packet from the server, the SYN gateway forwards the packet to the client and sends the ACK confirmation packet to the server in the name of the client. At this time, the server enters the connected state from the semi-connected state. When the client confirms the arrival of the packet, it forwards if there is data, otherwise it discards it. In fact, the server has a connection queue in addition to maintaining the semi-connection queue. If SYN attack occurs, the number of connection queues will increase, but the number of connections that the general server can withstand is much larger than the number of semi-connections, so this method can effectively reduce the attack on the server.徐海每每带队杀入几分，身后便又会围来更多的明军，己方始终被压缩在一个很小的空间内。3.
