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.这就是年轻人，这就是拓荒者，泱泱中华从不缺乏进取与冒险，只是历时过久皇族为求只身苟安，自缚枷锁，保住了朱家或者是爱新觉罗的子孙，却扼杀了其余全部的炎黄子孙。李左车将越军送来的信函交给齐王的时候，韩信不由有些怔了。对此，徐荣还是颇有疑虑的，毕竟和越王尹旭有矛盾仇恨的是周家，而羊非他徐家，这可以说是一段死人恩怨。NBC宣布一口气续订《#芝加哥烈焰#ChicagoFire》三季。---　　人类在这个小小的行星（他们称之为“地球”）上，建立了两百多个不同的行政区域（他们称之为“国家”），直到地球上诞生了第一个会思考的机器人。
