something i always wondered about Congestion Control and Network Monitor


Recommended Posts

theres something i never understood about Congestion Control and Network Monitor

maybe its a bug, maybe my R1 is faulty setup by me or i just always understood the green slider and its % in the wrong way lol

 

when i set congestion control to 70% (so 30% to the console) and i download a game on the console, the game downloads with 70% of my connection

when i set the percentage to 10% the game downloads with 10% of my upload

when i set the precentage to 100% the game downloads with 100% of my connection

share excess ticked

 

that is not how it should work i guess, it should be the other way round from my understanding

when i set congestion control to 30% the game should download with at least 70% of the connection but its just downloading with 30%

 

 

 

i always have my PC running in the meantime and as it seems the R1 is regarding the PC as the "gaming device" and therefore puts it under the congestion priorisation

i can confirm this, for the PC its the entire opposite:

 

when i set congestion control to 10% i download at least with 90% of my connection

when i set congestion to 90% i download at least with 10% of my connection

 

 

 

 

or did i get the green % slider in congestion control totally wrong?

i thought it works the following

green bar = bandwidth for any other device (= listed % number)

remaining grey bar = bandwidth you assign to the gaming device, so when the slider is set to 70% your console has 30% dedicated to it and the other 70% remain for all other devices

Hi Od1n,

 

The sliders on the congestion control page control the bandwidth for all devices.

 

To dedicate bandwith specifically to your console use the Device Prioritisation.

Hope this helps :)

yes i read that but its but it can be interpreted in both ways, it isnt really nailed down in its explanation imo

so how is the following picture to see?

1) 70% for all other devices, 30% reserved for gaming devices

or

2) 70% reserved for gaming devices, 30% for all other devices

 

from my experience yesterday as described above it seems to be 2) but the written text indicated towards 1)

When you set the cap at 70% you cap the whole connection to 70% of what ever you  entered into congestion control. This means there is no local congestion. The 30% that is left is not used for anything which is the whole point - it means the network does not become saturated.

I thought whatever your bandwidth was from your isp was decreased to only 70%.  For instance if your bandwidth was 100mb down/100mb up if you place the slider at 70% the your bandwidth would be throttled to 70mb down/70mb up.  I think only Iain can give us a definitive answer.

The Wiki also says that it "restricts the total amount of bandwidth that devices in your home can use". See here.

 

I've also updated the article pollutionblues posted to clarify that.

I've always thought it worked how Buck described it

When I download from Usenet using the full 70% my son who is gaming then uses the 30% that is free and his pings stay low.

 

Fully tested and working.

It flips into the spare "share excess"

 

You're talking about the device prioritisation aren't you? I thought we were talking about the anti-flood.

ok so what of the two is it now lol

 

 

When I use up the full 70% of my connection the 30% that was not in use gets used by my son

Pretty sure share excess is only for device prioritisation (as it is in that section) and therefore only works for upload anyway :)

So you were using the full 100% of your download bandwidth?

I think it works but putting a final cap on the bandwidth. E.g you have a 10mpbs connection and enter that into congestion control, if you cap it at 70% on the anti-flood you will only be able to use 7mbps.

 

There may be exceptions to this when the Netduma priorities gaming packets but I don't think that would be measurable if it was the case.

I download from Usenet which means I can max my connection

 

I set my cc to 70% which correlates to what I see in my Dl speed

 

But my son can still stream or game even when I have maxed the 70% out

 

Maybe I am tripping ;)

if I'm wrong I'll hold my palms up as I've have a few Amber nectars

 

I've never seen the Dl speed lessen when he streams and I'm doing a 1080 p film Dl but again this could be skewed and I'm wrong

It could definitely be me that is wrong, if it is then I'm sorry for shedding misinformation. What you're saying makes sense and I can't think of a reason that what your saying could happen without it using that 30% that is left over.

 

The reason I think it wouldn't do that (or at least wouldn't use up a significant amount of that 30%) is because then the network would become saturated and there would be queuing (or at least that is what I thought).

Hey I could be wrong mate I flood my connection at 70% when I Dl movies and TV shows and my lad does not blink an eye lid since I bought the Duma ,

 

It could be that it is ducking slightly below the 70 when he is on but it keeps my ping at 15ms on reactive no matter if I flood the 70% I am sure Iain will tell me I am talking out my **** but since I got the Duma I can flood the 70% with my Dl and he never bats an eyelid when In the past he would kick off :) saying dad I'm lagging are you dling a film

The no lag makes sense as that is what is meant to happen by setting it to 70%. But not sure how it works where it doesn't decrease the speed of the download - the only way that could happen if it was using the 30%. But if it works it works :) Hopefully Iain/Fraser can explain exactly how it works.
