See https://www.cs.kau.se/tohojo/cake/ - the link to the data files near
the bottom of that page also contains the Flent batch file and setup
scripts used to run the whole thing.
(And there's no explicit "number of bytes sent", but rather the flows
are capacity-seeking flows running for a limited *time*).
