I'm sure it's present, as a capability. I just think it's not being used (based on what I see for upstream bloat, which is >100ms without running cake in the router). On Tue, Jul 6, 2021 at 3:28 PM Wheelock, Ian wrote: > The support for AQM (PIE) is mandatory in D3.1 modems regardless of the

I'm running an Odyssey from Seeed Studios (celeron J4125 with dual i211), and it can handle Cake at 1Gbps on a single core (which it needs to, because OpenWRT's i211 support still has multiple receive queues disabled). On Tue, Jun 22, 2021 at 12:44 AM Giuseppe De Luca wrote: > Also a PC Engines

Re: [Bloat] Really getting 1G out of ISP?

The support for AQM (PIE) is mandatory in D3.1 modems regardless of the US mode in use (ie sc-qam (3.0) or ofdma (3.1) upstream), so it should be enabled. Get Outlook for Android From: Bloat on behalf of Aaron Wood Sent: Tuesday, July

Re: [Bloat] Really getting 1G out of ISP?

Are these in-flux changes to where the upstream split is why some modems report DOCSIS 3.1 downstream, but only 3.0 upstream? (and therefore aren't enabling AQM on the upstream?) -Aaron On Tue, Jun 22, 2021 at 4:04 PM Livingood, Jason via Bloat < bloat@lists.bufferbloat.net> wrote: > > For

Sorry, I should have been more clear. Not a fixed butler matrix but a device with solid state, programmable, phase shifters, 0 - 360 degrees. It's a way to create multiple phy channels and affect and vary the off diagonal elements of a MIMO H-matrix using conducted parts. Then automation software

Re: [Bloat] Credit and/or collaboration on a responsiveness metric?

In coming up with metrics, I would really encourage you to think about making use of tdigest to gather statistics in some of your on-line measurement. I'm not sure users see "average" behavior. I mean if someone is getting great latency numbers most of the time, with a small percentage of

Re: [Bloat] [Starlink] [Make-wifi-fast] [Cerowrt-devel] Due Aug 2: Internet Quality workshop CFP for the internet architecture board

We tried adding in an external butler matrix in the past, but could not notice any useful difference. Possibly we didn't have the right use case. Typically we are competitive on price for full testing solutions, but you can get stand-alone attenuators cheaper from specialized vendors. Happy

Re: [Bloat] [Starlink] [Make-wifi-fast] [Cerowrt-devel] Due Aug 2: Internet Quality workshop CFP for the internet architecture board

The four part attenuator part would be more interesting to me if it also had a solid state phase shifters. This allows for testing 2x2 MIMO testing per affecting the spatial stream eigen vectors/values. Bob PS. The price per port isn't competitive. Probably a good idea to survey the market

Hello, I am interested to hear wish lists for network testing features. We make test equipment, supporting lots of wifi stations and a distributed architecture, with built-in udp, tcp, ipv6, http, ... protocols, and open to creating/improving some of our automated tests. I know Dave has some

Hi I agree on Sebastian’s points on DOCSIS being able to offer this 100/100 service, as well as what the most recent version of what DOCSIS can do.. In terms of DOCSIS 3.1 it supports “High Split” upstream where signals operate up to 204MHz (from current limits of 42MHz, 65MHz or 85MHz). This
