Default prioritizing bandwidth, is it possible?

i have 5 computers on my home network and what i would like to do is give 100% of my internet connection to which ever computer requires it.

example; i have computers named, A,B,C,D . D is used for downloading and is quite the hog at using internet, it will use as much as is availible. now computer C is for checking emails and possibly downloading. so now i need to shut down D usage and hand it over to computer C. so now computer D has 1% and computer C has 99%. until computer B needs to be used then B will be 98%---C will be 1%----D will be 1%. and so on. and when traffic stops then it has to give 100% back to computer D

is there a way to do this in real time? can this be solved with a QOS router?

please, i dont need advice like "well just shut down the computers you arent using" or "set them on timers to download during the night". i have been doing things like this for a long time and it is driving me crazy and its why i am here posting trying to get this straightened out.

I have never heard of anything like this or a situtation where this was needed. Sorry. (I know this is a worthless post, but I just wanted to let you know people are reading it).

I haven't either. Bandwidth is just a set number... amount of information to pass through... I don't think we have networking hardware smart enough to partition certain amounts to certain nodes. Maybe that would be a good masters thesis or doctoral dissertation for an Information Systems guy

if the downloading that you're doing is via a program like bit torrent then yes you could use QOS to give preference to the web traffic and leave the bit torrent traffic on a lower preference.

I don't know if it's possible to use QOS based on a port, but it might be possible to use QOS on an IP address, I'm reasonably sure we're doing something not unlike this for a customer where I work. I'll see if I can have an ask about with the networking guys.

Default Re: prioritizing bandwidth, is it possible?

well thanks everyone for reading and offering what you can.

i think that port proritizing would work equally as well. so far the only options i can find are to just "reserve" speed for set applications. i dont want to give 10% of my internet for 100% of the day to a VOIP application just in case i get 1 phone call a week. this seems very inefficient.

would i have any easier time trying to just prioritize port numbers? i would have thought it would be easier to just shuffle everything to whichever IP/computer "asked" for it

ill try to describe my network maybe it will make an answer clearer

#1 is the VOIP phone, this is number one and when i get a call i want 100% or as close to it as possible
#2 the wife computer, this one hardly gets used and is mostly for emails, banking, not very demanding even at full use
#3 is a computer hooked to the tv so i can stream tv shows and movies
#4 my computer , same as my wifes computer except some downloading but not much
#5 downloading computer, thats all this thing does is upload and download all day everyday

right now if i download anything on #5 then i cant stream or use the phone and my wife starts barking because her computer slows to a crawl.

i have enough right now if i can just shuffle it around. right now i have to shut down the programs on certain computers or just shut them off. then the other computers work. even if i pay for the 10/mb/s service i would still use it all up on the download/upload computer and i would be right back where i am now except with a bigger internet bill every month

Why not just set a limit in your downloading program to only use 3/4 of it or whatever. Sure it wouldn't be as fast but at least you'd be able to use the other computers....

idk, i'm just throwing out ideas.

I agree, more bandwidth isn't the best solution...


you have a downloading program that will eat whatever bandwidth gets thrown at it...

at the same time, if nothing but the downloader program is using the line then you just want it to eat all the bandwidth it can.

QOS can do this. you;re not reserving half the line for voip or web browsing, you're prioritising that traffic, IF it is present.

Default Re: prioritizing bandwidth, is it possible?

Your bandwidth is being eaten alive by your streaming video and the upload/download computer. I have to assume the up/down computer is a peer 2 peer. You can limit the numbers of workers in the program you're using. As for the streaming TV programing, If you have cable why are you using this method? You can set up to have the media downloaded and stored for later playback. If you do that download in off peak hours around your house that will save on bandwidth needed for other uses.
But if you continue in the way you currently are configured, I would suggest getting a T-x (a 1, 2, or 3) line drawn in to your home. They're pricey but have the bandwidth and passthrough you need.

Default Re: prioritizing bandwidth, is it possible?

the thing is that i know if i throw a ton of money at this problem i can solve the problems i am having, running a T1 line seems like a step in the wrong direction. if i have more bandwidth then i will want to upload and download to its capacity still and i will be right back at the first post except i can start off by saying "i have a T1 line i am downloading on and my voip phone is choppy and streaming tv shows is choppy, but i have a firehose of a internet connection"

i would like to be able to get more bandwidth from my isp but first i need to figure out how to prioritze the speed that i have now.

yes the download program i use is p2p and also torrents and yes they both have options to set specific torrents and speeds and times during the day it is used. this seems like not a very good solution. i want it to download and upload like crazy the second im not using the network, example; im sleeping or working or leave for an hour. then when i come back it stops downloading while i check my email or get a phone call. then fires back up again. to me this seems like a far more effeciant system then restricting the programs to certain times or limits.

"root" you are the first person to say that i can do this with a QOS router, which router will do this and is easy enough to use, and preferably as cheap as possible. i am holding out on buying a router because i would like some real world advice on which options i need on a router to perform these sfunctions. will any QOS router have these adjustable settings? it seems like i can get a qos router for 50$ and from there the sky is the limit right up to commercial stuff. there seems to be a pretty big range

Default Re: prioritizing bandwidth, is it possible?

I think that a better explanation of the problem is that you want 100% utilisation of your line all the time...

when nobody is using any other machine you want to download at 100%.

when you want to use the web, then you want the connection to split, so that your web browsing is guaranteed bandwidth, and your downloading still happens, albeit at a slower rate.

whilst you're loading a page you want that to happen as quickly as possible, then whilst you're reading the page, you want the download to pick up again at full utilisation for the five minutes you're reading the page.

AFAIK, QOS is the only way to do this.

You can set bit torrent traffic at best efforts, and other stuff as marginally higher.

Your machine for checking mail, assuming that you're using IMAP or POP you can set this at just higher than the best efforts setting.
that way pop/IMAP will take precedence over bit torrent...

you want to set web traffic as the highest priority traffic, then your wen browsing computers get the best connection...
unfortunately, if you use web-mail then protocol based QOS won't differentiate between machine C or B or A as you listed above...

but lets face it, the traffic there is so low that you needn't worry. you won't max out a connection loading your inbox page...



with regards what router to buy...
this really is a case of RTFM, you need to select one in your price range, then read the manual to find out whether it does QOS, and whether it does it in the way that you want. what settings are available and how to set them up...

I'm assuming that you'll be fairly lost if you're having to create telnet sessions to your managed switch to edit the config. so you may wish to opt for one with a web interface.

ok so there isnt "different types" of QOS? ill start looking at one for what i need

is there any way via software or hardware to see graphically which computer is using bandwidth in real time?

assuming you have an intelligent switch.

You should be able to monitor the ports traffic, either by logging onto the switch or by using SNMP polling.

as before, if you want a switch that does this, make sure you read the manual before buying the switch so that you can determine how you do this, and can make sure that you can do this.
