Visitor pattern decouples the data structure from the operations acting on the structure, making the operation set relatively free to evolve. Visitor pattern is suitable for systems with relatively stable data structure and easy change of algorithm. Because visitor mode makes it easy to increase algorithm operation. If system data structure objects are easy to change and new data objects are often added, visitor mode is not suitable. The advantage of visitor mode is that it is easy to add operations, because adding operations means adding new visitors. Visitor mode centralizes the relevant behaviors into one visitor object, and its changes do not affect the system data structure. Its disadvantage is that it is difficult to add new data structures. -From Encyclopedia

For example, the buttons on the page and so on, For example, how to operate the specified buttons, What happens when the button is clicked, We don't know, We don't know what their business is. Of course, what we know will definitely be a click event. We don't know exactly what business to deal with. Here we can use command mode to deal with it: after clicking the button, we must send requests to some objects responsible for specific behaviors, which are the recipients of the requests. However, at present we do not know what the receiver is or what the receiver will do. At this time, we can use command mode to eliminate the code coupling relationship between the sender and the receiver.

As shown in the above figure, the server side provides NTP service. Attacker sends an NTP monlist Request to the server, but its source IP address is not its own IP address, but the IP address of the target. After the server receives the request, it will send a Response message to Target (not Attacker). Since Reponse contains 600 time synchronization records with Server, which is much larger than Request and consists of many messages, amplification is realized.
