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).(未完待续……) show_style();。越国骑兵在途中设伏，突然发起进攻，周和自然不敌。电影讲述了十年前两个留守儿童性格泼辣的燕子（郑湫泓 饰）和逆来顺受的陈路（卿雯 饰）在遇到在乡村支教的张老师之后，人生发生了转折的故事。
