Since these large numbers of hosts can continuously increase or decrease and can change their IP addresses and their connections, it is still a challenge to prevent such attacks.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.A1.1. 5 Sensory examination.开心女鬼郑裕玲，整蛊作怪、笑料百出！1941年日本人肆虐中原，与汪伪政府狼狈为奸疯狂杀害共产党人，我党损失无法估量。为完成民族解放大业，共产党人毅然在硝烟四起的战场予以敌人迎头痛击。同时建立起发达的地下网络截取敌人情报、消灭反动人员。这些英勇的地下人员就像一道汹涌的暗流推动着抗战胜利的进程。
