Facing TCP's three-way handshake protocol, how should attackers launch attacks? The attacker first intentionally initiated a handshake packet. After receiving it, the server puts it into the waiting queue and returns an acknowledgement. Secondly, the attacker will no longer send the third acknowledgement packet, thus the server will make multiple retransmissions (the Linux system configures the number of retransmissions through tcp_synack_retries), consuming a lot of extra overhead, and the waiting queue will be occupied, even the waiting queue will be full, eventually causing the server to be unable to receive the client's request. This is the attack.

Considering N categories C1, C2 …, CN, the basic idea of multi-classification learning is "disassembly method", that is, multi-classification tasks are disassembled into several two-classification tasks to solve. Specifically, the problem is split first, and then a classifier is trained for each split second classification task. During the test, the prediction results of these classifiers are integrated to obtain the final multi-classification results. The key here is how to split multiple classification tasks and how to integrate multiple classifiers.
