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.2. Take an examination of psychology and pedagogy (generally, there are remedial classes at the registration point, and the teacher will help you draw the key points, but you must memorize them, because these key points can only ensure that you are on the verge of passing the exam; The examination is held every six months and the results can be retained for three years, so it is better to go through customs at one time.

It simply and roughly sends a large number of normal requests, exceeding the maximum capacity of the server and causing downtime. What I encountered was a CC attack. At most, about 20 IP addresses around the world sent requests in turn, with the number of requests per address ranging from 200 to 300 times per second. When I read the log, I felt that those requests poured in like a flood. In the blink of an eye, there were a lot of requests. In a few minutes, the volume of the log file increased by 100MB. To tell the truth, this is only a small attack, but my personal website has no protection, and the server is still shared with others. This kind of traffic immediately goes offline.
