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).

National key cultural relics protection units, the first batch of 4A tourist attractions in the country. Located in the west street of the city, it was built in 686, the second year of Tang Wu Zetian's vertical arch, formerly known as "Lotus Temple". In 738 A.D., Tang Xuanzong ordered all states in the country to build a Kaiyuan Temple, which was changed to its current name. The whole temple covers an area of 78,000 square meters. It is large in scale, spectacular in construction and beautiful in scenery. It was once as famous as Baima Temple in Luoyang, Lingyin Temple in Hangzhou and Guangji Temple in Beijing. There are mainly buildings such as the Main Hall of the Great Hero, the Ganlu Ring Altar, and the East and West Pagodas. The Main Hall of the Great Hero is the main building of the central axis. It was built in the second year of the Tang Dynasty (686 A.D.). The existing building is a relic of the 10th year of Chongzhen in the Ming Dynasty (1637 A.D.). The main hall is 20 meters high and preserves the magnificent architectural style of the Tang Dynasty. Ganlu Ring Altar was founded in the Song Dynasty and is now rebuilt in the early Ming Dynasty. It is one of the three largest ring altars in the country. Standing in the squares on both sides of Baiting, the octagonal five-story pavilion-like wood-like stone pagoda, which is about 200 meters apart, is Quanzhou's East and West Pagoda and is one of the four famous towers in the country. The East Tower is called "Zhenguo Tower" and has a height of 48.24 meters. The name of the West Tower is "Renshou Tower", with a height of 44.06 meters, slightly lower than that of the East Tower, and its scale is almost exactly the same as that of the East Tower. The two towers are treasures of ancient stone structures in our country and are symbols of Quanzhou, a famous historical and cultural city.
