What is the effective bandwidth?
Effective bandwidth is a real speed at which data can be transmitted to connection. This is unlike the theoretical maximum that the connection can carry. Originally The efficient bandwidth was used in a link to dial -up devices, although this term can also be used for permanent connection, such as broadband internet providers. Each customer connected to the local exchange will have the maximum possible speed available to connect them. However, if each customer connected this speed simultaneously, the amount of bandwidth that went through local exchange would be very and extremely expensive. It is very unlikely that this will happen, so the connection is not set for it. The selected limit will be a balance between the highest demand it expects, and you are threatening to maintain low costs. This usually means that there will be situations, for example at the time of peak, when the total bandwidth of the required customers exceeds what has been made available. This means that customers will suffer slowThe effective bandwidth will be noticeably slower than their maximum bandwidth.
However, there are many other reasons beyond artificial limits why the bandwidth can be lower than that maximum. The simplest thing is that the data will be slower if they have to travel. This may mean that the efficient bandwidth varies between users in different places.
Another problem is the way the data is sent in packets. It is a small batch containing a part of the data sent, plus information to identify the sender and recipient, and a control sum of the errors, which is the mathematical equivalent of the check list to ensure that the data is arrited. At each intersection on the route around the network, the entire packet must arrive before it can be checked and then directed in the next stage of your journey.
delay between the first part of the packet arrival and the last part of the coming slowTotal speed. This means that the effective bandwidth is inevitable slower than the theoretical maximum. There is also a possibility of delay when two or more packets arrive at the same gate at the same time, which means that they must effectively create a queue that is also known as a buffer.
