Usually, the initial serial number of the server is calculated by the server according to certain rules or adopts random numbers. However, in SYN cookies, the initial serial number of the server is obtained by hash operation and encryption of the client IP address, client port, server IP address, server port and other security values, which is called cookie. When the server suffers from SYN attack and makes the backlog queue full, the server does not reject the new SYN request, but replies the cookie (SYN serial number of the reply packet) to the client. If it receives the ACK packet from the client, the server subtracts 1 from the ACK serial number of the client to obtain the cookie comparison value, and performs a hash operation on the above elements to see if it is equal to the cookie. If equal, complete the three-way handshake directly (Note: At this time, you don't need to check whether this connection belongs to the backlog queue).高中毕业前最后的暑假，富樫勇太（福山润 饰）和小鸟游六花（内田真礼 饰）依然过着平静的生活，只是两人的关系似乎没有更进一步的苗头。在此期间，六花的姐姐十花在意大利找到工作，遂决定举家迁往海外。而面对重度中二病患者的妹妹——连上大学都成问题的六花，作为姐姐的十花无论如何不放心将她一个人留在日本。得知要和六花分开，勇太内心充满焦灼。
