Cookies technology does not need to allocate space at all when receiving a SYN. Because the most basic data that make up the connection state are encoded and compressed into the sequence number bits of SYN-ACK. For a legitimate connection, the server will receive an ACK message segment with a serial number (actually the serial number has been added by 1), then the basic TCB data will be regenerated, and a complete TCB will confirm that the data will be safely instantiated through decompression. This decompression can be successful even under severe attacks, because there is no storage load at all on the host side, only the load that calculates the encoded data into the ACK sequence number. The disadvantage is that not all TCB data can be added to the 32-bit sequence number segment, so some TCP options required for high performance cannot be encoded. Another problem is that such SYN-ACK message segments will not be forwarded (because forwarding requires complete state data).
