The goal of Xplico is extract from an internet traffic capture the applications data contained. For example, from a pcap file Xplico extracts each email (POP, IMAP, and SMTP protocols), all HTTP contents, each VoIP call (SIP, MGCP, H323), FTP, TFTP, and so on. Xplico is not a network protocol analyzer.
Braa is a mass snmp scanner. The intended usage of such a tool is of course making SNMP queries – but unlike snmpget or snmpwalk from net-snmp, it is able to query dozens or hundreds of hosts simultaneously, and in a single process. Thus, it consumes very few system resources and does the scanning VERY fast.
