Consider the network shown below where terminals A$,$ B and C are communicating over a bus. The distance between stations A and B is $2$d meters. The distance between stations A and C is $4$d meters.The propagation delay between stations A and C is t sec and between A and B is t$/2.$ Frames arrive atthe three stations and are to be transmitted at stations A$,$ B$,$ and C at the respective time t A $=0.$ tB $=$ tand to $=$ t $2.$ Frames require transmission time of $2$t$.$
