Can someone explain the differences in bandwidth? Im kinda boggled by that at the moment. What I mean is I understand 300gb of bandwidth per month, but how mang gb is a megabit? And whats it mean to be burstable? Sorry if this sounds rather stupid, but network operations isnt my thing really...

ok let me help you alitte..... about 300gb of transfer is 1 megabit..... now burstable means this... Sometimes you are capped meaning you can only download from your website at the capped number... lets say your capped at 1 meg a second... that is the fastest you will ever download... Now burstable means that you can go as fast as the line will carry.. you are not capped at all... meaning you are using the full 100megabit port to transfer... however usually with that they charge you by how many gb u transfer... hope that helps.

So my 300gb cap is what im actually dealing with. The burstable megabit is just the speed of the switch/routers im on?

Two different methods of measurement. 300gb is a fixed amount of traffic. You can send 300gb in a day and thats it.

If you are billed on an average utilization (t-1 being 1.5mbps) and burst over that, but the average utilization for the month is less than your maximum, you wont get overbilled.

300gb could be calculated to a specific average transfer by breaking it down into 30 days (10 gb per day), converting to Kbytes then dividing that by 24 then by 60 then by 60 to reach your actual "sustained averaged k/sec" you are allowed. In that respect it is the same as a burstable limit, but you'll usually find the number is lower than the big 300gb # appears :)

So if a company is offering my server 300gb/mo transfer fully burstable, it basically means im restricted to 300gb/mo, and not capped by any speed except that of the switch?

Correct. If you are on a 100mbit or gigabit port and they have the bandwidth, you could use that up in a day ;) Then they would charge you.

I'd prefer a capped limit personally, something like a evil reseller or a DOS attack/ping flood, could leave you holding the bag.

REMEMBER: OVERAGES are where hosting companies make their money. Read your contract on liability. If i open up 100 simultaneous wgets to some files for a while, to your box, whose responsible? You? Read the contract. I pay about $10K/month for unmetered DS3 (including loop charges) (2 of them for bgp 4 redudnancy) . If i was an evil person i could easily run your bill up.

I dont do this of course, unless requested (Security load testing/DOS testing).

Just keep in mind Who is responsible for what, cause you could be playing with fire.

If you have a switch like a 2924 you can place between your servers you could possibly cap maximum throughput, so your users might get a lagged out throughput, but your bill wouldn't be out of this world.

Also remember, isp's make money overselling bandwidth, its the only way. If i had a DS3 and its not at 90-100% throughput in both directions, i'm wasting $$..

Back in the days we used to shove 1024 vhosts into a t-1 running at 100% 24/7, and made good cash doing so ;) No shame in hussling. The company was very profitable.
