| how bandwidth is shared... Hello Forum,
Bandwidth (data rate) is a shared resource for some type of internet connections.
I have this analogy in my mind that bandwidth is like water through a pipe. When we go to a coffee shop and there is free internet through a Wi-Fi connection the coffee shop users can all surf the web at the same time.
A certain amount of total bandwidth is available to the shop (say 10 Mpbs) like a pipe of water of a certain size. This water can then be shared among the users.
How does this water analogy actually translates into the technical terms of bandwidth sharing? Bandwidth means data rate.
Is there a highly modulated signal coming in that then gets split into lower modulation signals if there is the need to accommodate multiple users?
What device allow the users to share that bandwidth?
If there is only one user at the coffee shop surfing the internet then he/she will get all the bandwidth. But if other people jump in his connection (download speed) slows down.
How does this process of allocation actually works?
thanks,

| You need to think in digital terms not analog. There are are all sorts of mechanisms that can be used but the simplest mechanism is first come first serve.
Packets arrive from multiple sources. As each one arrives it is placed in the first in first out (FIFO) queue. On the transmit side the transmitter peels off packets one at a time. When it has finished transmitting one it goes back for the next, and so forth.
