In TCP implementation, when receiving the SYN request from the client, the server needs to reply the SYN + ACK packet to the client, and the client also needs to send the confirmation packet to the server. 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).以「如果可以通过胎儿基因检测是否为精神病患者，肚子里的孩子被确认是患者，您是否会选择生下来？」为主题所展开的故事。将不同于以往精神病题材的电视剧。黎水盛了两碗汤，对她道：大哥，咱们以汤代酒，来喝一碗。他们三人于现代经历一次又一次的冲击，性格与价值观亦渐渐改变，随后更因难得一遇的异象即将发生，而面临人生最严峻的考验与抉择……大局已定，签订封神榜吧。//Since the single pattern is instantiated only once, the following instances are equal
