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.　　说的故事发生在明朝，当时，秦淮河畔夜夜笙歌，南京城里就有一条著名的街道，“春秀街”，之所以被贯以这个名字，因为此地乃是单身男女汇集拍托的场合，被誉为南京城最令人神往的地方……两人的命运交汇，最后唱出的歌是希望？是绝望？还是……在青青草原世界，After the attack occurs: analyze the cause of the attack and locate the source of the attack.简·芳达和莉莉·汤普林主演的Netflix剧集《同妻俱乐部/格蕾丝与弗兰基》宣布第5季上线时间：明年1月18日。“她们回来了，也没什么可在乎的了！”依旧聚焦两个特殊的老年闺蜜：她们被告知丈夫都是gay，并抛弃了妻子在一起，两个女人也发展出友谊。她们这个年纪的生活有独特的味道，也有自己的危机。
