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.　　三个孩子在营救马大爷的过程中与飞虎队相遇，却因为互不相识擦肩而过。为找到孩子们，鬼子大张旗鼓，飞虎队却只能暗中寻访。大壮有承诺在先，只把情报告诉老洪一个人。飞虎队不敢冒然表露身份，大壮的一根筋让鬼子和飞虎队都陷入困境。　　卡维泽所饰演的角色名叫Reese，他在秘密行动中所受的特殊培训得到了爱默生的角色Finch的注意。Finch是一名软件天才，他发明了一种可以使用模式识别即将行使暴力犯罪族群的程式。用这种国家最先进的监视技术，这两人游离于法律之外，用Reese娴熟的特工能力以及Finch无限的财富，揭开那神秘的犯罪嫌疑人，并在犯罪发生之前制止它。Demo Man--> Diao Shen Man--> Know Principle Man--> Know Principle + Can Change Model Details Man--> Super Large Data Manipulation Man--> Model/Framework Architect秦旷……英王……出身书香世家，有一个当尚书宰相的大伯父、当地方大员的爹，他比谁都清楚，英王将来继承大统的可能性。尹旭先派出蒲俊，率领一支千人的精锐，先行渡河，抢占河滩登陆。1.
