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.RQ1, …《乔省长和他的女儿们》不是大家所熟悉的类似于《官场现形记》的名利追逐故事，实际上它是在讲述一种情感，讲述对亲情和生命价值的再思考是这部亲情伦理剧要探讨的核心思想，“生命价值是通过个人的经历来体现的。剧作关注作为社会人（从技术员、矿长、市长、巡视员、厅长，到最后的省长）的乔良在人生的不同阶段所面对的问题和思考，通过他的个人成长和心灵的完善过程，看到他所代表的那一代人的生命轨迹……在日本天皇宣布投降的前夕，一小股残暴的日军在犬养大佐的命令之下，疯狂的向江城大桥进发，不顾一切的准备炸毁江城大桥。当时与军统局少将主任万汉源共事的地下党精英杜康接获了万汉源的电报指示，不惜一切代价护桥，同时万汉源更指示杜康请求江北八路军支持守护桥头镇，原来杜康的共党员身份在万汉源面前早已曝光。In fact, "robbing news" itself is also part of journalists' "news literacy".JGJ79-2012_Technical Code for Foundation Treatment of Buildings _Construction Code.
