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.

As the server's network equipment, routers, switches and other infrastructure have a certain upper limit on the processing capacity of data packets, when the arriving data path packets exceed the corresponding upper limit, the problems of network congestion and slow response will occur. Attackers can use this feature to control a large number of hosts to send data packets to the target machine, causing network equipment to be busy, making normal requests unable to be responded to in time, resulting in denial of service.

Therefore, amateur trainers do not take part in any competition, and their high results will not affect their life and future. Protective equipment should be used as soon as possible. Only by nipping in the bud can we have better training and avoid interruption of training due to injuries, which will affect our work, study and life. Other knee pads or something, use them when you feel stressed, and take them when you can get used to them. Don't be afraid of how much that knee pad will affect your grades. For amateur trainers who squat for more than 2 times their weight, change into a better belt and keep a pair if conditions permit.
