A textbook which says:
The bandwidth-delay product defines the number of bits that can fill the link. This measurement is important if we need to send data in bursts and wait for the acknowledgment of each burst before sending the next one. To use the maximum capability of the link, we need to make the size of our burst 2 times the product of bandwidth and delay
I'm a little bit confused, let's say we have an example as the picture shows below:
So according to what the textbook says, I need to send a burst of data of 50 bits, I understand it is a waste of bandwidth to send a burst of data that is less than 25 bits, but what's the difference if I send the burst of data of 100 bits, 200 bits ... etc?
