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).

This can reduce the coupling between customers and specific implementations.
"As far as I understand it, If a mouse is the size of a domestic cat, But also rushed up in droves, It should be very dense, The goal is quite large, According to the weaponry at position 149, I don't feel too stressed, If you cooperate with the large "killer bees" to form an open space, you can also deploy some firepower to use tracer armour-piercing firebombs to the air and other weapons to the ground, whether it is a step machine gun, or rocket launchers, recoilless guns, as long as the command is proper, fire shooting, resist the attack of a group of mice, I think it is not too difficult? Is this kind of big mouse not only large in size, but also able to withstand bullet attacks? Or are they too fast to be easily hit? " I am somewhat puzzled by what Zhang Xiaobo said. He said his point of view, See if he has any answers, With the experience of strange dogs in position 142 interviewed earlier, Plus he just said that the rat moves quite quickly, So I preconceived that he would say that the reason why these mice are difficult to deal with is similar to that kind of strange dog, because the speed is fast and the movement is flexible, which leads to low fire killing efficiency and short reaction time, which leads to great pressure on position defense. As a result, I didn't expect him to give an answer that is not any one of my many assumptions:
