However, if the real-time data of the system is not very high now, we can collect all ID for a period of time (e.g. 2-3 seconds) through a proxy function and send AJAX requests to the server at one time. Relatively speaking, the network requests are reduced and the server pressure is reduced.Is it TCP to try to send enough SYN packets and run out of backlog? The purpose of SYN flooding. The attacker added the source IP address to the SYN packet, which would not cause the host to remove the assigned TCB from the SYN-RECEVIED state queue (because the host would respond to the SYN-ACK). Because TCP is reliable, the destination host will wait quite a long time before disconnecting the half-open connection and removing the TCB from the SYN-RECIEVED queue. During this period, the server will not be able to respond to legitimate new TCP connection requests from other applications. Figure 2 shows a simple TCP?
