(i) Suppose N stations are connected to an extended Ethernet LAN, as shown below shown in Figure operating at the rate of 10 Mbps. Assume that the efficiency of each Ethernet is 80 percent. Also assume that each station transmits frames at the average rate of R bps, and each frame is equally likely to be destined to any station (including to itself).
a) What is the maximum number of stations, N, that can be supported if R is equal to 100 kbps?
b) If the bridge is replaced with a repeater, what is the maximum number of stations that can be supported? (Assume that the efficiency of the entire Ethernet is still 80 percent.)
