1Mbps = 1024 / 8 KB/s = 128KB/s.
Getting 140KB/s means they are giving you more than 1 Mbps.

Understanding contention ratio's
- Thread starter Shayd
- Start date
1Mbps = 1024 / 8 KB/s = 128KB/s.
Getting 140KB/s means they are giving you more than 1 Mbps.
ok let me explain again
Old connection - home package 1mbs 10:1 contention ratio; 120kbs to 140kbs - R500pm
New connection - Business Package 1mbs 1:1 contention ratio; 120kbs to 140kbs - R1000pm
this is at the same isp both packages are uncapped unshaped so what i want to know is if my isp is taking me for a ride or i have the wrong understanding of how contention ratio works

Wrong understanding. Contention ratio means that if your co-client is downloading, you will get less due to the available pool of resources being used up.
What you are paying for is a 1Mbps (128KB/s) connection at certain contention ratios. What you actually want to do is get a faster connection instead of improving the contention ratio.

Contention ratio in your case means that you have a dedicated 1Mbps up/down link from your premises to your service provider - 1:1 - and you are not sharing equipment on their side either.
Where you share a link with other users, your speed would depend on the number of other users on the same link at the same time. If all 10 were using the link at the same time your service would be slow.
Personally I would revert to the "home" package at a higher speed.

1mbps line is 1024 kilobits, and then devide by 8 to get bytes, give you 128
So in a perfect world with a 100% link you can achive 128 kilobytes per second. So if you get more, then they gave you a bigger link.
140 would give you 1120 which is 96 more than what the suppose to give you.
So between you and the SP you have 101% of the 1mb line, so they give excelent service.
Then the contention ratio is the amount of users, like yourself that they assign certain bandwidth to, so 1:1 mean they allocate 1024 from their backbone to internet just for you.
1:4 mean the allocate the 1024 to 4 users from their backbone, so if everyone in this group download at 100% you'll get 32kbps
But because the chance is slim for all 4 users to-do that, plus the fact that the SP gets a 80mbps link and share it, means you would proberly never get lower than 100 even when network is busy.
I would go back to 1:10 and save money, and only when you never get your full bandwidth, then upgrade the contention ratio

Just as a note, the contention ratio isnt between you and the SP, that is always 1:1, unless you and a neigbour share the same equipment, but in 99% of the time each client use his own equipment, thus no contention between you and their datacentre

"This is a measurement of the number of other subscribers you are "contending" with for your share of ADSL bandwidth leading to your local exchange. For example, the contention ratio as published by Telkom is 20:1, this means that you would share your bandwidth with no more than 20 subscribers on the Telkom Network."
and what you saying is just not making sense and if i understand what you people are telling me the ISP's dont make any sense lol\

I thought you have a wireless solution, and here is some DSL story.
What is the answer you are looking for?
I can try, if i understand what you are after!
its exactly the same description my isp gave me its not online tho its on a document they sent me and before i upgraded i sent them a mail asking if ill have much higher speeds on 1:1 and they said yea you will so i came to this thread to get a better understanding about what im dealing with just so i can sort things out and that they cant bull**** me 'well its seems they already did'
