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.　　父亲与狗同时走丢了，到底要先找谁？警察秘密组织——“特殊班”的王牌刑警——川久保稜（松田翔太饰），背负着弟弟亡故和从小没有母爱的过去，一边破案一边寻找失踪的妈妈。而宋（李泰民饰）原本是医大高材生，和女朋友过着幸福的生活，却因为一场脑部实验失去记忆。两个境遇截然不同的男人，以“特殊班”成员的身份奔走在疑难案件中，他们都爱上了命运的女主角绫辻佳菜（泷本美织饰）……为了保护研究，男子将身体交给了浑浊的潮流…Fire shutter　　期盼着和平的国家，而成为了土耳基史上最年轻的将军。
