PureInsight Flow Analysis is used to create network streams from the PCAP files. Streams are plotted based on 5-tuple information, which contains source/destination IP, source/destination port, and timestamp extracted from each packet. The streams are plotted as number of packets (y -axis) vs time (x-axis).
