SYN flooding attacks can attack with fewer packets than ordinary brute-force DoS attacks that only send a large number of packets to the target network. However, this requires some understanding of the server's operating system, such as how much backlog queue space it allocates and how long it will keep the TCB in the SYN-RECIEVED state before timeout and discarding the TCB. For example, an attacker can send a certain number of SYN packets that are exactly the size of the backlog queue, and their cycles are just the time when the TCB is recycled, thus making the server permanently unavailable.

From the above command class code, we can see that any operation has an execute method to perform the operation. The above code uses traditional object-oriented programming to implement the command mode. The procedural request call of the command mode is encapsulated in the execute method of the command object. Have we found the above writing code a little cumbersome? We can do this using the callback functions in javascript, In object-oriented, The receiver of the command mode is saved as an attribute of the command object, and the command execution operation is agreed to call the command.execute method. However, if we use the callback function, then the receiver is closed in the environment where the callback function is generated, and the execution operation will be simpler. Only the callback function can be executed. Let's look at the following code:
