Packet-level classification: classify based on packet
Per-packet-split: Mix all packets and split them into train, val, and test sets, based on 8:1:1
Per-flow-split: Split the pcap files based on 5-tuples (src_IP, dst_IP, src_port, dst_port, and protocol), using 3-fold validation, and there is no intersection between the train, val, and test sets.
