Round 2 Tarball: http://www.drhleny.cz/bufferbloat/cake/round2.tgz <http://www.drhleny.cz/bufferbloat/cake/round2.tgz>

*** Notes/Analysis ***

* bql tests similar to last time:

* 8/8 flows tests and n/n flows tests in general still a bit mysterious with too much for me to unpack:

* first voip tests with irtt show it’s working, but these will be more meaningful at lower rates:

* still don’t think I managed to get udp flood to work, must be doing something wrong:

* new cake host isolation tests across a range of RTTs show fairness improvements up to rtt 20ms, then nothing significant after that:

*** Round 3 Plans:

* Use netem to test a spread of simulated rtts and bandwidths.
