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.一个宅女,两个男朋友,江湖从此多事。《好想做一次》隆重回归,推出第2季,7月15日在Netflix上线。[Doctors involved in "Tucao Hongmao Medicated Liquor" are expected to obtain a guarantor today pending trial.
