In this configuration, the only traffic is a TCP connection between h1 and h2, with no packets being artificially dropped on the links (but packet losses may still be caused by buffer overflow). You will use topology topo3.py, which corresponds to a long fat pipe, with a larger bandwidthdelay product than in the previous configurations. Type sudo E python topo3.py to run the topo3.py script, and type h1 iperf c h2 t 60 > i1.out at the CLI prompt. Q8. From what you learned in the lectures, what is the available bandwidth from h1 to h2? Based on the TCP throughput reported in i1.out, how well does TCP fill the available bandwidth? Note that mininet measurements do not necessarily have pinpoint accuracy, but the approximate values should be good enough to draw a conclusion
