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.他心情忽然就好了起来：也许，这个张富说不定哪天会带给自己一个惊喜。Set up position, quantity and fire emergency broadcasting system diagram.Is a network card, an IP,胡钧顿时眼窝发热、鼻头发酸，竭力忍住，才没落泪。　　由颜丹晨领衔主演的电视剧《山里红》目前正在东北拍摄当中。这部戏正
