He=E2=80=99s probably referring to the tendency of non-flow-isolating = AQMs to drop packets indiscriminately when under load. Cake is flow-isolating and thus applies a separate AQM algorithm to each = flow. As such, UDP gaming/VoIP traffic won=E2=80=99t get dropped unless = it exceeds its fair share of the link, which is unlikely for a = well-designed, lightweight protocol. We really should make an effort to put a more intuitive GUI interface on = this. These questions indicate a user overwhelmed by many options = without guidance. - Jonathan Morton
