a) Assume each router implements FIFO queuing. If each flow consists of an identical, 1-Mbps constant bit rate UDP flow with equal packet sizes, what will the resulting rate be for each flow? You can assume that FIFO drops packets with uniform probability.
b) Now consider the case where all routers implement fair queuing. What would be the throughput of each flow now?
c) Finally, assume all routers implement WFQ, and each flow is assigned a weight equal to its number (i.e., flow F4 gets weight 4). What are the resulting throughputs?
