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.
For example, if the duration of induction is 15.3 seconds, then the number of times of induction is 30, the time is 15.5 seconds, the number of times is 31, the time is 15.7 seconds, and the number of times is still 31

The other two schemes are based on SYN cache and SYN? Cookies (see 6.4), simplifies the state initialized when the TCB is generated by receiving the SYN, and delays the instantiation of the full state [4]. In hosts that use SYN caching, a HASH tablespace with a limited size is used to store a subset of data that will be allocated to the TCB. If the ACK is received when the handshake is completed, the data will be copied into a complete TCB, otherwise HASH values exceeding the lifetime will be recycled when needed. In Lemon's FreeBSD, the SYN cache is 160 bytes for a half-open connection, while a full TCB is 736 bytes and supports 15,359 SYN cache spaces.
