What is the meaning of contention ratio?
Contention ratio refers to the maximum demand divided by the actual bandwidth available on a connection. The higher the ratio, the larger the number of people on the same “pipe”, as it were.
What is contention ratio in networking?
In computer networking, the contention ratio is the ratio of the potential maximum demand to the actual bandwidth.
What does high contention mean?
When your contention ratio is high – meaning a lot of people are connected to the same line as you – it can potentially drag down your broadband speeds. That means that if you’re in an area with a high contention ratio, you’ll probably get slower speeds in the evening when more people are online.
What is the contention ratio in ill?
Contention Ratio (or over subscription ratio) is the number of users sharing the same data capacity. The lower the contention ratio the higher the quality of service. A 50:1 contention ratio means that up to 50 broadband customers are sharing the same bandwidth at any one time.
What is WiFi contention?
Channel Contention – Can be defined as 802.11 mechanisms to gain access to the medium to trigger frames. In other words, CSMA-CA. CSMA-CA is the rule book or referee used by WiFi devices to gain access to the medium.
What is a good contention ratio?
A contention ratio of 1:10 means that you share available bandwidth with 10 others and you have a guaranteed speed of 1. The best contention ratio is a 1:1 (a low ratio). A low contention ratio means that more bandwidth is available to you on the network at any time.
What is the contention ratio of Airtel?
The regulations for consumers are 1:50 and 1:30 for residential and business customers respectively. In other words, if I have 100 megabits of bandwidth to the outside world, I can supply no more than 5,000 residential customers.
What is BT contention ratio?
Broadband Contention Ratios is the total number of households sharing the available bandwidth on an internet/data connection. The lower the number, the better the quality and speed of the connection.
Is FTTC contended?
FTTC is a contended broadband service so at peak times there may be a drop in performances as you are sharing the service with other users in your area.
Does Fibre have a contention ratio?
Contention ratio is not really an issue for fibre because a fibre connection is much faster than a standard ADSL service and is capable of supporting far more users at one time, to the point where any limitations on speed caused by a high contention ratio are minimal.
What is the contention ratio in the UK?
In the UK, an RADSL (Rate Adaptive Digital Subscriber Line) connection used to be marketed with a contention ratio between 20:1 and 50:1 within the BT network, meaning that 20 to 50 subscribers, each assigned or sold a bandwidth of “up to” 8 Mbit/s for instance, may be sharing 8 Mbit/s of downlink bandwidth (to your home).
What is the contention ratio in computer networking?
In computer networking, the contention ratio is the ratio of the potential maximum demand to the actual bandwidth. The higher the contention ratio, the greater the number of users that may be trying to use the actual bandwidth at any one time and, therefore, the lower the effective bandwidth offered, especially at peak times.
What’s the contention ratio for a 100MB line?
If the line you have access to is a 100Mb one, for example, you can easily get average speeds of around 35Mb or 63Mb on a good day. But if your contention ratio is 50:1, with 50 people connected to it, and you’re all using it at once… you’ll only get speeds of about 2Mb.
What should the contention ratio be for BT?
Standard contention ratios used to be around 50:1 for home broadband, and 20:1 for business broadband – but BT says these figures are no longer completely accurate. When your contention ratio is high – meaning a lot of people are connected to the same line as you – it can potentially drag down your broadband speeds.
