Theoretically 6/1mbps, with RTTs ranging from 700 - 1200ms. From the cake technical page "The AQM layer has no configuration options. However, it is planned to add simple tuning options for different prevailing RTTs that may be significantly different from the Internet-scale 100ms currently assumed. Satellite links tend to impose longer RTTs, and enclosed LANs tend to have much shorter RTTs." Does this imply cake is not yet ready for use on satellite links? Or merely that I'll get sub-optimal results but it's still worth testing? I see I could set the interval in sch_cake.c and recompile - is there any reason why this would be a bad idea? Am I right in thinking with such observed variation I'll get better results setting for the lower limit (700) rather than the upper (1200)? Any suggestions for a more sane target to set while I'm doing this?
