Another end-host-based solution is to shorten the time between a TCB entering the SYN-RECEIVED state and being recycled because it does not enter the next state. However, an obvious disadvantage of this scheme is that the attack can take advantage of ACK-SYN lost packets due to congestion or ACK packets completed by handshake, so that legally connected TCB will be recycled because the host is busy retransmitting these packets (because SYN-RECEIVED time is reduced). In addition, there is only a linear relationship between how much time the administrator reduces the SYN-RECEIVED state and the attacker's contract awarding rate. For the above reasons, this scheme is not recommended.(未完待续……) show_style();。自张角死后，天下并没有归于太平，少帝被废，年幼的献帝即位，却只能做个傀儡皇帝。一切朝政大事都由董卓一手掌握，民众终日生活在水深火热、提心吊胆之中，导致民不聊生，曹操遂与刘备、关羽商议前往洛阳刺杀董卓。曹操用自身的行动证明了正义终将战胜邪恶，集体利益永远大于个人利益，一切妄图以一己之力破坏民族安定的人最终都会得到应有的报应。This is a place where the construction of a new socialist countryside is quite effective.
