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).
