The SYN-Flood attack is currently the most common DDoS attack on the network, It is also the most classic denial of service attack. It takes advantage of a defect in the implementation of TCP protocol. By sending a large number of attack messages with forged source addresses to the ports where the network service is located, it may cause the half-open connection queue in the target server to be full, thus preventing other legitimate users from accessing. This kind of attack was discovered as early as 1996, but it still shows great vitality. Many operating systems, even firewalls and routers, cannot effectively defend against this kind of attack, and it is very difficult to trace it because it can easily forge the source address. Its packet characteristics are usually that the source sends a large number of SYN packets and lacks the last handshake ACK reply of the three handshakes.看来这一遭想尽办法，力劝沛公攻陷武关实在是太英明了。国库虽然穷，当官的不穷，不说那些暗中参与的大小官员了，只说荣郡王和陈国公两家。关晓春、魏文彬、贾磊三人是大学同住一个宿舍的好兄弟，三兄弟性格迥异，一个张扬，一个内敛，一个单纯。从大学时代三人就开始共同创业，并小获成功。毕业后三人进入各自不同的岗位。而关晓春却不甘于平淡，辞职自己创业，致力于从事互联网电子商务。几年来，关晓春的事业随着互联网的发展起起伏伏，而关晓春的人生也跌跌荡荡。跟他多年的女友李薇与自己最好的兄弟魏文彬结婚，事业跌入谷底又再次起死回生，兄弟间因为误会反目，合作伙伴背叛，竞争对手打压，这一系列变故都没有击垮关晓春，始终坚持梦想，一路走下去。最终，关晓春的公司成功上市，三兄弟摒弃前嫌再次相聚在一起。
