The goal of Xplico is to extract the applications data from an Internet traffic capture. For example, from a pcap file Xplico extracts each email (POP, IMAP, and SMTP protocols), all HTTP contents, each VoIP call (SIP), and so on. Xplico isn't a packet sniffer or a network protocol analyzer; it's an IP/Internet traffic decoder or network forensic analysis tool (NFAT).
