No, loss is flat where bandwidth is maxed, they should - even with a log scale have a huge increase in loss when bandwidth is maxed. > > As for loss rate, may be the real "big" loss number is on another > interface in the chain. All I'm saying is the graph doesn't seem to back the assertions, and merely seems to be tracking a background errors on the link. Yes, I'd love the loss and delay numbers. > Sincerely, > > Laurent > -- Dave Täht NSFW: https://w2.eff.org/Censorship/Internet_censorship_bills/russell_0296_indecent.article _______________________________________________ Cerowrt-devel mailing list [email protected] https://lists.bufferbloat.net/listinfo/cerowrt-devel
