Suppose that three Ethemet LAN's are connected with two bridges as shown in Figure 1 below. Each Ethernet LAN operates at the rate of 10 Mbps, and assume that the efficiency of each Ethernet is 80 percent (i.e., the maximum throughput on a LAN is 8 Mbps). There are Nhosts connected to each LAN (and a total of 3Vhosts). Each host transmits frames at the average rate of R bps, and each frame is equally likely to be destined for a host on one of the three LAN's. We are interested in the average behavior so assume that the bridges have learned the locations of all the hosts. For the topology in Figure 1, find the maximum value for N that can be supported if R is equal to 100 Kbps. (Answer: 34.)
