he figure depicts K sources which are connected to the Internet via links of capacity RS, and within the network fairly share a common link of capacity R to K destinations. Each destination is connected to the network by a link of capacity RD. You can assume that there are no other links or source-destination pairs in the network. Now suppose that source Si has an infinitely large file it wants to send to destination Di (i.e., each source sends to a different destination). a. If K=10, RS = 100 Mbps, Rd=10 Mbps, and R = 10 Gbps. What is the throughput between each source-destination pair? Where are the bottleneck links? If we now assume that K=10, RS = 100 Mbps, Rd= 100 Mbps, and R = 0.5 Gbps. What are the new throughputs between each source-destination pair? Where are the bottle-neck links
