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.

It was an instructor with a telescope who looked through the telescope and saw that the thing was a lot of mice. And they are all very big, After the news spread throughout the position, I have all my comrades, All ready for battle, Knowing that this is like one of those big wasps, It is certainly not a good fault, Just thinking of starting to fight the newcomers when it comes closer, I didn't think they were about 100 meters away from the position. It stopped suddenly, At the beginning of digging holes collectively, I felt that they were digging holes faster than running on the flat ground. One by one, they almost disappeared from the ground in an instant. Soon, a large area of dark mice disappeared.
