Reflective attacks typically use protocols that do not require authentication or handshake, The reflection attack needs to forge the source ip address of the requested data into the ip address of the target. If the protocol used requires authentication or handshake, the authentication or handshake process cannot be completed and the next attack cannot be carried out. Therefore, most reflection attacks are carried out by network services based on udp protocol.
Case: For example, for an important work at different stages, due to its importance and time constraints, the Company specially held a special coordination meeting to clarify the work that various departments need to cooperate in the implementation, and also stated that various departments should fully cooperate, and sometimes even directly authorize the responsible persons of the departments concerned to have special rights to coordinate the overall work. However, when cooperation is often needed, the situation will not be as fully coordinated as stated at the meeting. Dispatching a person needs to ask for instructions from the person's department head. After contacting the department head, the department head also needs to ask for instructions from the competent leader. If the leader arranges, it will be implemented.

From the above analysis, it can be seen that this situation can be counted as situation 2, but I feel that it is clearer and more reasonable to separate it separately. When analyzing situation 4, I will also explain some reasons. At the same time, this is also an application of the first two situations. If I understand situation 1 and situation 2, many other situations not mentioned in this article can be explained.
Action: I don't remember what I ordered. Forget it and open it (what if I threw it away directly?)
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
