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.Editor's comment: The BMW 3 Series has a total of six generations of models since its development.

The overall structure of the new BMW 3-Series chassis makes it worthy of the title of the same control benchmark. Compared with this, what makes people feel more valuable is the emphasis on chassis details of the new BMW 3-Series, and it is this spirit of pursuing perfection that enables the BMW brand to have a strong foothold for a hundred years.我脑子又没毛病，跟你赌这个。1959年的四月十六日，对于51858部队一营营长石峰来说，是一个既难忘又庆幸的一天。石峰美貌的妻子给他生了一个大胖小子，更让他合不拢嘴的是寻找多年的救命恩人梁步贵也终于让他找到了。对于石峰来说，儿子和梁步贵在他心目中有着同样重要的位置。生性豪爽、做事干练的石峰根本就和举止文雅、满腹经纶的梁步贵不是一路人。在石峰的眼里，梁步贵就是一个弱不禁风的秀才；而在梁步贵的心目中，石峰无非是一个头脑简单的莽夫。石峰一直认为梁步贵胆小怕死。可是在朝鲜战场上，梁步贵在关键时刻挺身而出，舍身救己的行为彻底让石峰改变了对他的看法。两人负伤后，不久石峰又重返了前线，而梁步贵因为伤势过重被送回国内医治。就这样，两个人一别就是7年。生死至交久别重逢，喜悦心情难以言喻。可当石峰得知梁的近况后，深深的自责敲打着他那颗善良的心。梁步贵和冬柳结婚后一直没有自己的孩子。经医生检查才知道，就是当年在战场上掩护石峰而落下的病根。梁步贵这一生也不能再生育。当他发现妻子冬柳渴望有一个自己的孩子时，他才意识到这一辈子他欠妻子的这份情1.
