Facing TCP's three-way handshake protocol, how should attackers launch attacks? The attacker first intentionally initiated a handshake packet. After receiving it, the server puts it into the waiting queue and returns an acknowledgement. Secondly, the attacker will no longer send the third acknowledgement packet, thus the server will make multiple retransmissions (the Linux system configures the number of retransmissions through tcp_synack_retries), consuming a lot of extra overhead, and the waiting queue will be occupied, even the waiting queue will be full, eventually causing the server to be unable to receive the client's request. This is the attack.
Decorator mode focuses on stable interfaces and extends functions for objects on this premise.

The 23 design modes, in fact, the predecessors have summed up the ways to solve the problem. Their aim is to ensure the low coupling and high cohesion of the system. The principles guiding them are nothing more than the design principles of packaging change, single responsibility, interface-oriented programming, etc. After that, I will continue to share my WCF learning process. Although there are many WCF series in the blog park, I felt that it was not necessary to write them before, and I felt that I could use them. However, I did not write them. I always felt that the knowledge was not my own and I did not feel in-depth. Therefore, I still want to write such a series. I hope all bloggers will support me more.

A friend taught me a method that impressed me deeply. A cloud service provider promised that each host would protect attacks below 5G traffic, and they bought five at one go. The website is set up on one of the hosts, but it is not exposed to the users. The other hosts are mirrored and are used to face the users. DNS will evenly distribute the traffic to the four mirror servers. Once there is an attack, this architecture can prevent 20G of traffic. If there is a bigger attack, then buy more temporary hosts and continuously expand the image.
