Black Box Log, BBLog, or (historically) NFLX or Netflix log, is a logging format that uses custom PcapNG blocks, and custom options on PcapNG packet blocks, to record logging data related to the network connection.

The Private Enterprise Number (PEN) for these blocks and options is 10949, the PEN for Netflix, the originator of the format. It has since been incorporated into FreeBSD Ports as the output format of tcplog_dumper.

Source Code

As of this writing, dedicated BBLog blocks are dissected by packet-bblog.c, and BBLog options on standard packet blocks are handled by packet-frame.c.
