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.当国内恐怖分子威胁到洛杉矶的命运时，哈利·博施必须在迄今为止风险最高的赛季中拯救这座城市。The essence of the division of the three worlds is a classification based on the different levels of development, political systems, historical and realistic relations of various countries in the world.
