In the previous example of electric lights, a state mode program was completed. First, the Light class is defined, which is also called Context here. Then in Light's constructor, to create instance objects for each state class, Context will hold references to these state objects in order to delegate the request to the state objects. The user's request, that is, the action of clicking button, is also implemented in Context, with the following code:

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? The process of a SYN flooding attack.
