Dave I feel like you're rather optimistic about the deployment of fq Also, you mention uplink in home gateways. There you not only have bittorrent but also a lot of personal cloud going up, a lot of video calls.
There IW10 without fq is going to be bad. In the US your are going to have pie on cable if I am not wrong...uhm...

One saving grace of the IW10 deployment so far is that it is (mostly) limited to Linux, and that methods, such as pacing/initial spreading/fq, to cope with it better, are developing concurrently. It's not all bad - on GigE ethernet networks, it's ok, IW10 may well be useful in wifi packet aggregation, etc, but it does do potentially a great deal of damage to networks running at very low rates. My concern has largely been the collateral damage it causes network uploads from the edge, where vastly lower rates are common. It could be mitigated further in a desktop deployment by (for example) sticking with IW4 for everything going out a default gateway, and steps taken to make sure applications like bittorrent/transmission used a lower default. I have no idea what the IW is for android, but that should perhaps be lower also. I think ledbat shouldn't have an IW at all.... I would not mind if IW information was carried as a payload in dhcp/hnetd/etc... I have no problem with people suggesting changes here that require "changing the entire internet". We seem to have done that a couple times, already. :) It would be nice if we could calculate the damage it causes along whatever portion of the internet is running at below 10Mbit.... A simple question - how many T1 lines are left in the world? > -- > Mikael Abrahamsson email: [email protected] -- Dave Täht https://www.bufferbloat.net/projects/make-wifi-fast _______________________________________________ Bloat mailing list [email protected] https://lists.bufferbloat.net/listinfo/bloat _________________________________________________________________________________________________________________________ Ce message et ses pieces jointes peuvent contenir des informations confidentielles ou privilegiees et ne doivent donc pas etre diffuses, exploites ou copies sans autorisation.
