I/O multiplexing refers to using a thread to check the ready state of multiple file descriptors (Socket), such as calling select and poll functions, passing in multiple file descriptors, returning if one file descriptor is ready, otherwise blocking until timeout. After getting the ready state, the real operation can be executed in the same thread or thread execution can be started (such as using thread pool).

The Interface Segmentation Principle (ISP) means that it is better to use multiple specialized interfaces than to use a single total interface. That is to say, don't let a single interface take on too many responsibilities, but should separate each responsibility into multiple specialized interfaces for interface separation. Too bloated an interface is a kind of pollution to the interface.

SYN attack is a kind of DOS attack. It takes advantage of TCP protocol defects and consumes CPU and memory resources by sending a large number of semi-connection requests. SYN attacks can not only affect hosts, but also harm network systems such as routers and firewalls. In fact, SYN attacks can be implemented as long as these systems turn on TCP services no matter what systems are targeted. As can be seen from the above figure, the server receives the connection request (syn=j), adds this information to the unconnected queue, and sends the request packet to the client (syn=k, ack=j+1), then enters the SYN_RECV state. When the server does not receive an acknowledgement packet from the client, it retransmits the request packet and does not delete this entry from the non-connection queue until the timeout. With IP spoofing, SYN attacks can achieve good results, Typically, clients forge a large number of non-existent IP addresses in a short period of time, SYN packets are continuously sent to the server, and the server replies to the confirmation packets and waits for the confirmation of the customer. Since the source address does not exist, the server needs to continuously resend until it timeout. These forged SYN packets will occupy the unconnected queue for a long time, normal SYN requests will be discarded, the target system will run slowly, and in serious cases, the network will be blocked or even the system will be paralyzed.
