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.亚莉克莎与凯蒂第四季……当初令狐冲也是不断找人治伤，但是结果……结果天下第一神医平一指都自杀了。第二天早晨，醒来的他们眼前出现的景象是……Your sketchpad is too small尹旭这小子真有两下子，竟然和范家也扯的上关系，这么贵重的宝剑也轻易送人，莫非范家是看中了尹旭？尉缭叹息一声，轻声询问。讲述的是丞相之子黄明昊为了追得公主，追随皇上微服出宫，查明亲爹要谋朝篡位的故事。
