What speed should I get from ...
 

Hi guys. I know the normal relationships between bits and bytes, but I don't know what NTL supply on their packages. It seems that they double some conncetions etc etc.

So, what speed should I expect to get from a 750Kb connection? About 80KB per sec?

Cheers.

there's nothing different about NTL's bandwidth compared to anyone else's.. if you use the bits - bytes relationship as you say you already know... then the figure you get from that calculation would be accurate

512 * 1000/1024 * 1460/1518 * 1/8 = 60 kBytes/sec
750 * 1000/1024 * 1460/1518 * 1/8 = 88 kBytes/sec

etc

As S1lv3r has already said, the calculations are straightfoward enough.

Bear in mind though that you won't always get a constant (or even particularly high) download speed. You may be connected to a slow server (particularly on P2P networks) and in that case your downloads will be slower.

FWIW I often get speeds of about 80k when I'm using BitTorrent.

NTL used to supply double speed on their 128k service to customers who had a STB connection for BB. They got 256k whereas SACM connections got 128k.

NTL specify service levels in bitsx1000 or bitsx1,000,000 for services faster than 1Mbit/s, thus

300 = 300,000 bits/sec
750 = 750,000 bits/sec
1.5 = 1,536,000 bits/sec

Divide the figure on the right by 8 to get the maximum bytes of data you should expect per second. Remember that data communication is always done in bits though, it's when it gets to your computer that bytes become important. Also those are *maximum* figures - you won't always get them.

Thanks All.

It's good to have it in black and white.
