Visitor mode is to encapsulate some operations applied to a certain data structure. Once these operations need to be modified, the data structure that accepts this operation can be saved unchanged. Visitor mode is suitable for systems with relatively stable data structures. It reduces the coupling degree between data structures and operations acting on data structures, making the set of operations relatively free to change. The specific structure diagram is as follows:

On the other hand, the rapid development of the application of the Internet seven-layer model has diversified the attack targets of DDoS. From the web to DNS, from the three-layer network to the seven-layer application, from the protocol stack to the application App, the endless new products have also given hackers more opportunities and breakthrough points.

Often, the construction cost of a business's DDoS defense system is larger than the cost or benefit of the business itself, which makes many start-up companies or small Internet companies unwilling to make more investment.

This part of the work is completed by each group of broadcast routing protocols. All hosts participating in multicast must implement IGMP.
