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.不过这年头还是冷兵器时代，只有弓箭，曹无伤自然没有听说过,所以他注定了聪明反被聪明误，反误了卿卿性命。项庄疑惑道：会是谁呢？范增摇头道：老夫也想知道会是何人？总而言之而且那一句秦国余孽潜入军营让柳成心中大震，不由自主的便对号入座想成是自己了。
