神仙有问题。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.His greatest characteristic is "mental retardation". Once in class, the teacher asked us to write a composition.
