Reset authentication takes advantage of the reliability of TCP protocol, and DDOS protection system responds to syn first. When the protective device receives syn, it responds to syn_ack and sets the Acknowledge number to a specific value (recorded as a cookie). When the real client receives this message and finds that the acknowledgement number is incorrect, it will send a reset message with a sequence number of cookie + 1. The source of the forgery will not have any response. In this way, we can add the real client IP to the white list. ?

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 refers to allowing an object to change its behavior when its internal state changes. The object seems to have modified its class. Divide this sentence into two parts by commas. The first part means to encapsulate the state into a separate class and delegate the request to the current state object. When the internal state of the object changes, different behavior changes will be brought about. The second part is from the customer's point of view, the object used has completely different behaviors in different states. The object seems to be instantiated from different classes, but in fact this is the effect of using delegates.
In programming, Sometimes it is necessary to generate a large number of fine-grained class instances to represent data. If we can find that these instances are basically the same except for a few parameters, if we can move those parameters outside the class instances and pass them in when the method is called, we can greatly reduce the number of individual instances by sharing the website invariant
