Instead of something = like "High(250ms) RTT" be like "Inter-continental", medium(100ms) RTT = may be "Intra-continental", and low(50ms) RTTs may be "Local Region". = "Region" can be a bit ambiguous, but I figured if given two options = "Local Region" and "Intra-continental", that the idea of what "region" = represents in this context is clear enough. Satellite links would only = need one option because the latency of the satellite will be greater = than the latency from all of the terrestrial links combined. As for the = actual variable name and not the option names. hmmm. Assuming similarly = named options, "Optimize for"? > [...] For the crowd on this mailing list any names will do, but for novices = that just heard of buffer bloat and its remedies, I believe we need = simple unambiguous names. The challenge with distance is that while = geographical distance should not be too hard to figure out, path = distance is much trickier (aka true user will need i measure). If I = recall correctly, codel is actually pretty robust against deviations of = true RTTs from interval, but I do not remember any data showing this on = a per true RTT basis or for fq_codel (where I assume the issue might be = more pronounced, as the different RTT flows will be separated unlike in = codel where all is mixed).
