Bandwidth Calculating & Pricing
I need to co-lo a server and I am getting such conflicting information on bandwidth that I thought I'd ask here.
I am being quoted, say, $99 per megabit. Does this mean that I can push 1 megabit per second for an entire month and my cost is $99?
BTW: not everyone uses the 95 percentile method.

I currently have a server on 5Mbps on the 95th percentile connected to a 100Mbps pipe. So I can burst as much as I want to 100Mbps.
If it's on the 95th, then you technically have a little over 300GB usable bandwidth.

Yes EasyProSys you can push 1mbps per second for the entire month without getting charged more. Try talking to your host and ask if they can do GB billing, as that's much more comfortable and allows you to burst more.
Edit: this is my assumption, ask your host for clarification so there are no surprises.

Basic colo you will see providers offering it in GB more than mbps typically. You can find colo depending on the market between $75 and $150 a month with anywhere from 1000gb to 2000GB starting.

Thank you, but that wasn't the question.
If I am being quoted, say, $99 per megabit. Does this mean that I can push 1 megabit per second for an entire month and my cost is $99 for the month?

It gets so confusing because in the past I was charged using the 95 percentile method and if I was hitting 20Mb/s my provider thought it was an attack and shut me down. Or I was being charged on overage fee. Now I have a quote for 6000GB per month but no clear answer on how many megabits that is. I need to know because the pipe is 100Mb/s. If the pipe is only 100Mb/s could I ever hit 6000GB? We'll be pushing video and 400 connections at 256kbps will hit 100Mb/s.
Honestly, I just don't know how to do the math.

With per GB billing you should be able to push the full port speed, though expect some overhead so don't calculate your available bandwidth as a full 100mbps.
Video at 256kbps is pretty choppy quality, but I guess you're doing something like YouTube with low res. If you can leg it for a 1gbps port it would be perfect, as you'd have quite a bit of room when you receive a large traffic burst.

If my math is correct, on a 100Mbps pipe you can theoretically hit almost 31TB of throughput at 100% utilization 100% of the month(30 days). Somebody double check my math, its 2:13AM. :-P
I know its waaaaaaaay more than 6,000GB

yes, you will hit 100mpbs and actually exceed it if you could, you would max the port and thus your users will get latency and crappy speed you need a 1gbps port. But how much actual transfer depends 100% on how long you sustain those 400 connections. If you sustain 100mpbs all month long you will do roughly 32,000GB.

Sorry to be so dense, but how do we know that 10Mbp/s = 3200GB per month?

We use math, and some bit knowledge, and leave some room for overhead.
1megabits per second = 128 kilobytes per second
128*60*60= 460800 kilobytes served per hour at 1mbps constant rate (460 megabytes)
460 megabytes * 30days * 24 hours = 331200 megabytes (331 gigabytes)
Multiply by ten and you get 3310 GB per mo. for a 10mbps line, but we subtract some because it's just theoretical and because of overhead you will never push the full amount.
Multiply by ten again and you get the theoretical amount for 100mbps which is 33100GB.
I should have just directed you to Google .

1Mb/s for 24 hours is 86,400Mb/s, or 10.546875GB. That equals 316.40625GB per month. Times 10 equals 3164.0625GB. For 100Mb/s that's 31,640.625GB.
Close enough. I used online calculators.
MY HEAD HURTS!!!
Sorry if your head hurts now.

I'm used to these sort of questions, which is why we're only dealing with per GB pricing on our servers and offer bandwidth blocks in 1TB packs, as it helps people know how much traffic they can use and to avoid the hassle.

IIRC, on average, most people can push 150-200GB per Mbps. It doesn't mean you can really push 300GB in 1 Mbps, as you can't possibly expect 24/7 of consistent usage pattern.

Wrong. 1 byte = 8 bits. Hence,
1000000 bits = 125000 B
125000 B = 122.0703125 KB
122.0703125 KB = 0.119209289 MB
1 minute -> 0.119209289 MB * 60 = 7.152557373 MB
1 hour -> 7.152557373 MB * 60 = 429.1534424 MB
24 hours -> 429.1534424 MB * 24 = 10299.68262 MB = 10.05828381 GB
30 days -> 10.04 GB * 30 = 301.7485143 GB
Round off to 3 sig. figures = 301 GB per 1 Mbps.

The error is at 1 mbps = 128 kB/s, should be 125kB/s, the total data pushed out is lower, but still somewhere in that area.
