Is it TCP to try to send enough SYN packets and run out of backlog? The purpose of SYN flooding. The attacker added the source IP address to the SYN packet, which would not cause the host to remove the assigned TCB from the SYN-RECEVIED state queue (because the host would respond to the SYN-ACK). Because TCP is reliable, the destination host will wait quite a long time before disconnecting the half-open connection and removing the TCB from the SYN-RECIEVED queue. During this period, the server will not be able to respond to legitimate new TCP connection requests from other applications. Figure 2 shows a simple TCP? The process of a SYN flooding attack.《双室小吃车》改编自裴慧洙(音)的网络漫画，讲述了在深夜偏僻处出现的一个神秘的小吃摊的故事。Application layer attacks use more sophisticated mechanisms to achieve hacker targets. Application layer attacks do not use traffic or sessions to flood the network, but slowly deplete resources on the application layer for specific applications/services. Application layer attacks are very effective at low traffic rates. From a protocol point of view, the traffic involved in the attacks may be legitimate. This makes application layer attacks more difficult to detect than other types of DDoS attacks. HTTP flood, DNS dictionary, Slowloris, and so on are examples of application layer attacks.许久之后，林成洲才长呼一口气，长叹道。一座完好的营寨，还有许许多多的物资粮草全都交到了汉军手中……汉军此战从井陉口东征，韩信志在速战速决，行军速度和地形限制导致并未携带太过辎重物资。周菡踌躇了一下，道：那就进来吧。现代都市青年司马乐川在经历了女朋友、房东、导演的同时给予的多重打击后，在人生最低潮的时候，无意间因为一块小石头“喜神方”，穿越到了三国时期，在遇到刘备、诸葛亮、张飞、关羽等人，发了一系列既在情理之中，又意外百出的故事。在诸葛亮夫人黄月英、孙权妹妹孙尚香、周瑜夫人小乔的共同帮助下，保证了对历史一窍不通的司马乐川在历史的进程中没有出现偏差，没有对历史进行任何的篡改。同时乐川在一系列的时间旅程中，收获了丫鬟小懿的爱情、刘、关、张等人的友情，体会到真情的可贵。最后结尾处发现其实这一切都是有人在“别有用心”的操控着。留在三国的司马乐川以后还会发生怎么样的故事，《喜神三国》第二部将精彩继续。
