I tried googling in books dot google dot com for related materials on this, but was unable to find any. This is from kurose ross book and it's a bit convoluted. Can anyone guide me here a bit? I don't need exact answer but a way/place to look into.
Do you have metered on-ramps on the highways near you? otherwise look it up, consider the highway the wire, consider the on -ramps as the buffer, cars as the packets, the more traffic on the highways, the slower the signals are to allow the cars from the on-ramps onto the highway to their destination. thus allowing all traffic on the highway, eventually (delay), but not so much that the highways are no so much congested (at capacity) and packets dropped (cars crash).

You mean something like this, right? I am learning slowly.
yes but need a few more on ramps down the mainline.
