how do I figure how much bandwidth streaming audio, video, YouTube, etc use?

Some of my users and i are having a discussion about whether or not listening to online radio stations take up of our available internet pipe?

our pipe at school is a 6m ASDL line.  It is 6mb up and down if that makes a difference.  So if I have one user listening to a radio station, how do I determine how much of that 6mb they are using?  The same would hold true of video, youtube videos, etc.

I have been doing a google search but am having problems coming up with something in clear and simple language.  Also, we are not sending any streams, just receiving them.

I maintain that streaming anything actually opens up multiple connections to the internet and that is what uses up the pipe.  If so, then how do you figure out how many connections you have open?

Most of the articles i can find on the web are to techincal for my brain,  :'( so I figured someone here can translate this for me!   :Thmbsup:

thanks

I'm pretty sure Networx (free) will give you the info you want

I wasn't really looking for something like that Andy but that is good all the same.  I was trying to figure out if a radio station was streaming at 128 kbps, then is there a way to figure that is going to use say... 2mb of my pipe?  That is for just one user on my network.

sorry that I wasn't very clear.   :-[

skwire:
A 128 kbp/s stream will take up just that over time, 128 kilobits per second.  It's usually not a completely continuous stream since most players will cache a bit, play, cache a bit more, play, etc.  In other words, streaming audio stations typically take up very very little of your internet connection.  However, keep in mind that that is per user of said stream.

techidave:
So if I was understanding you correctly, then 10 users each streaming at 128 kilobits per second would then take up 1 meg per second??
