[Coral-dev] binary output format for crl_flow

[Ken Keys]

The preferred way to read them is with the Perl Traffic2 and Tables APIs,
which are documented in the online docs that came with coral and at
http://www.caida.org/tools/measurement/coralreef/doc/doc/index.html.
Ryan will correct me if I'm wrong:  I think the binary file format is
the same in 3.4.7 and 3.5, but 3.5 contains some improvements to the Perl
APIs, as well as making the fast C++ backend for the Perl APIs available
to everyone (not just caida members).
