The attacker first forged the address to initiate a SYN request to the server (can I establish a connection?) The server will respond with an ACK + SYN (Yes + Please confirm). The real IP will think that I did not send the request and did not respond. The server does not receive a response and will retry 3-5 times and drop the connection after waiting for a SYN Time (typically 30 seconds-2 minutes).

If an attacker sends a large number of SYN requests with fake source addresses, the server side will consume a lot of resources to handle this semi-connection, and saving traversal will consume a lot of CPU time and memory, not to mention retrying SYN + ACK on IP in this list. TCP is a reliable protocol, and messages will be retransmitted at this time. The default number of retries is 5. The interval time of retries is doubled from 1s to 1s + 2s + 4s + 8s + 16s = 31s respectively. After the fifth time is sent out, it will take 32s to know that the fifth time has timed out, so the total is 31 + 32=63s.

State mode and policy mode are like twins. They both encapsulate a series of algorithms or behaviors. Their class diagrams look almost identical, but their intentions are very different, so they are two very different modes. The policy pattern and the state pattern have in common that they both have a context, policies or state classes to which the context delegates the request to execute
