uploading VS downloading

I've thought about this until my head hurts...

Is uploading the same as downloading? (bandwidth-wise)

Yes.

What?

As far as I know, your download rate is always higher than your upload rate. All depends on your ISP. I don't know my stats for sure so I can't state an example.

no the majority of people who have broadband use cheap cable, which has close to non existant upload, which makes cable great for leeching

most dsl plans have the download rate higher than upload, but you can get plans that are like 512k/512k or 2048/2048 speeds, but you pay extra

One thing I can state for sure: I'm on DSL Lite (very ghey but still better than dial-up) And my max d/l speed goes no higher than 26/kps, while my upload rate goes no higher than goddamn 12 or 13/kps.....The rep for the DSl company gave me more detailed stats but in my old age, I forgot them.

server side software limits upload, the cable never changes

Ok, bandwidth-wise, theoretically speaking, there is no difference. Uploading does not magically take up twice the bandwidth, and vice versa.

In practical terms, some ISP's will put separate caps on upload speed/download speed. This is most apparent in the early satellite setups (might even still be true today, although I don't know anyone who still uses a satellite for internet service) where your download speed was limited only by the satellite's transfer rate (and the corresponding caps on the ISP's end), whereas the upload rate was limited only by the crappy modem you used in conjunction with it.

Going with the separate caps idea, most xDSL providers will put a cap on the download speed and a cap on the upload speed. Typically the upload speed is 1/2 to 1/4 the speed of the download rate in this situation.

Other companies will simply put a restriction on the amount of total bandwidth you can consume during any given second. In this case, your uploads will affect your downloads...high upload rates will reveal slower download rates, and vice versa. I don't know if the ISP does this or if it's just the way it's set up, but dial-up modems are also restricted in this way, afaik.

thats not what i meant

eh, wtf do you mean.



its the same bandwidth, however you usually have to pay when you upload, well thats what I saw when I was looking for T1 lines.


is that what you mean.

Dude just saying that it's not what you meant isn't gonna help us any...it's like a surgeon opening up your body while he/she looks for youe heart, except the surgeon starts at your foot and works up.

i delcare you a trollwhore!

At the college I go to, our T3 uses bandwidth plans. There are various amounts of bandwidth-per-week plans. Uploading + Downloading = Bandwidth used. That's how it works here.

768/256 download/upload is what I have. Upload is generally slower then download, it's a fact of nature.

lol @ the possibility of that theory being correct for adsl

lol @ the complete lack of understanding of the adsl nature here

and you call yourselves GEEKS?!?!

not everyone is as smart and godlike as you, you'll have to learn to live with it.

when will people end up being as good as me?

you do realize that its just a fucking piece of metal in a plastic coating, right? That the only thing that could possibly be limiting the rate at which electrical impulses shoot through it is software.

Limiting the rate, yes - but. Resistance, interference, and signal strength all affect signal quality as well. At the protocol level upstream and downstream transfers are identical, just reversed in directions. However, most in home technologies have limited available upstream bandwidth. ADSL= Asynchronous Digital Subscriber Line. Generally speaking, that means your upload will be significantly less than your download... Cable also has limited available upload bandwidth because it was designed to be a downstreaming technology.

ADSL as opposed to SDSL. SDSL is only required by some businesses since your D/U ratio equals to one. That is why it is more expensive.

itll just be slower and shitty. same speed both ways. Havent you ever used a home network? same speeds if your computers are fast enough...

attenuation and interference have nothing to do with the transition from upload to download.

Actually, ADSL is slower upstream due to hardware issues. It has to due with channel frequency density - upstream data takes place on a different part of the spectrum from downstream data, and in particular, channel losses/noise are more prevalent for that upstream frequency.

With computers we tend to think of bandwidth on software terms - however, you have to keep in mind that it still has a physical meaning in the hardware world. When we say that the upstream bandwidth is smaller than the downstream bandwidth, we literally mean to say that upstream data occupies a frequency range that is not as wide as that for downstream data - i.e. your uploads are going through a "narrower pipe" and therefore you can force less water (data) through it at the same speed. Also note that "speed" is the time it takes for the signal to get from point A to point B, whereas "bandwidth" is simply how fat the pipe is. I know you know this Orbax, but I'm explaining for those who don't.

SDSL, or Synchronous DSL, operates on a different principle, that being that downstream and upstream data both take place on the same portion of the frequency spectrum. So although you technically have the same bandwidth for downloads and uploads, the bandwidth is shared between the two of them so if you're downloading and uploading then your average transfer speed will be reduced.

Hope that clears it up.
