Question

Im trying to find if my internet service provider is giving me the bandwidth im paying for.

According to the contract, must receive 1030 Kbps. The compression ratio is 1:8 (I think this means that there is the possibility that 8 guys (including myself) can be connected simultaneously).

I carried out a test and the uplink and downlink bandwidth were 0.16Mbps and 0.04Mbps, respectively. So what I did was the following:

first: added the uplink and downlink banwith
Bt = DL + UP
Bt= 0.04 + 0.16 = 0.2

second: multiplied the total bandwith by 8

bandwith = 0.2*8 = 1.6MB

is that correct?

Answer 1

apparently, im reciving more than wha im paying for (that doesnt make any sense to me). In fact I am listening to the radio online and every minut it stops coz it needs to buffer. Radio does only need 35 kbps of bandwidth, so It must not happens (I think). I used 1 mega at college and it was completelly different.


I dont think in can be caused for vires, becasuse im using linux now. With xp connection is slow too

Answer 2

You are right about the compression ratio. You would get 1/8 of the 1030Kbps, but your addition is wrong. Your internet subscription specifies a download rate and an upload rate, these are either asymmetrical or symmetrical. Symmetrical would mean you have 1030Kbps down ánd 1030Kbps up. I assume your download speed is 1030Kbps. When the compression kicks in, you have 1030/8 = 128.7 Kbps. Which comes down to 0.13Mbps, which isn't much indeed.

Answer 3

It says that the uplink is 1030/8 and the downlink is 128/8

Answer 4

are you sure? usually it's the otherway around ( as consumers are mostly downloaders instead of uploaders)

Answer 5

sorry yeah it is downlink 1030 and 128/8 uplink

Answer 6

download 1030/8

Answer 7

Yes, in your case the lowest amount of bandwith you can get (due to the compression) is 0.13Mbps. Since not every has the same usage, your probably will have slightly higher speed usually, that's why you measured 0.16Mbps. But still, this is very low indeed.

Most internet radio streams at 128kb/s. If you do some other stuff on the internet while listening to internet radio, there's not enough bandwidth to buffer fully. Your best pick is using internet radio that streams at lower rates, like 32kb/s or 64kb/s.

Answer 8

For average internet usage (youtube/radio/email or smt) I think around 300 kb/s is ok. Anything lower will make you wait often.

Answer 9

In conclusion, they are giving me 1M right?

Answer 10

Yes, they are giving correct about (with respect to compression).

Answer 11

ok thank you very much for your help
