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).

Perhaps the moonlight is too bright, disturbing people's sleep. Tony opened it and watched someone help him tuck in his quilt. He evoked his mouth and smiled at Stephen without asking who the man was. Instead, Stephen opened his mouth first, "Doctor, Doctor Strange." Tony looked at the person in front of him through the moonlight and blurted out, "Are you... magician?" The overlapping memory made Stephen blush. Stephen nodded and watched Tony smile like a child. He seemed satisfied and turned his back to pretend to be mysterious and said, "Then we'll see you next time, Tony." He drew a circle with his fingers and opened the portal to meet the sanctuary.
