I need bandwidth explained to me. I have a colocated server on a plan that gives me 2000 GB a month. I have a radio station interested in shoutcast streaming 300 users 24 x 7, 128 kbps. That would be 12,441.6 GB a month if there are 300 users all the time.

So I'm going to have to buy more bandwidth, but I don't understand 1 mbps, 10 mbps, etc. My server is a Dell 1850, Dual 2.8 Xeon's, 2 Gigs RAM, RAID SCSI drives, etc, etc. It is connected to a 100 Mbps port. It can handle 300 users.

Should I upgrade to 10 mbps? How much bandwidth is this?

Thank's in advance!

10mbps is around 3 terabytes if maxed out all month. So you wouldn't be able to get 300 users at 128kbps on a 10mbit line. You'd need a 40mbit line approx to get 300 users connected 24/7 on 128kbps.

If you already have 2000GB of bandwidth and you're using 12.4GB a month on shoutcasting then you don't need to buy extra bandwidth. If you upgrade to 10mbps that will give you about 3000GB of bandwidth, but it looks like you dont need it.

Andrew didn't read the post properly :P

Assuming you were to use 12,441GB in a month 24/7

You'd need close to 40mbit of bandwidth (there is around 320GB in a 1mbit if I remember correctly)

Of course are you really going to have 300 users 24/7?

You'll need ds3(45mbps) or better for 300 128k subs/users.

That had better be one rich *** Radio Station.

How much would 40Mbit line actually be.

In UK I couldnt imagine paying that.

what could be it's cost

In a DC 2-6k usd

single line to a location 5k usd +

Average mbits are 320GB's but calculated with the 95% you'll be looking @ 200-250GB traffic.

That URL doesn't convert bandwith -> 95% measurement.

You could always risk it that the 2000GB will be enough. My guess is, the 300 listeners will rarely, if ever, be reached. Say they have 30 listeners on average, that will be less than 1300GB.

If you wanted to be 100% certain of your costs though, get a 40 Mbit/sec unmetered connection, which can run you less than $1k, unlike what some others have said. The max you need is EASY to calculate, 128k/sec x 300 listeners = 38,400 k/sec.

If you notice with the unmetered server that you never come close to the 40 Mbit/sec and just have infrequent spikes, etc. then you may want to consider saving some money and getting a system billed on 95th. Actually, going with a system billed on 95th percentile is likely your best bet, as I would definitely imagine their spikes will be for less than 5% of the time, though again, that brings some question into what your actual overall cost is again. It all depends on how much risk you are willing to take.
