Create several duplicate scenarios and modify the interarrival times for all the Ethernet stations to 0.0008, 0.002, 0.003, 0.005, and 0.006, respectively. Rerun the simulation, and record the Traffic Received (bits/sec) statistic for each scenario. Using a spreadsheet, plot the values, (together with the results you found in the preceding scenarios using interarrival times of 0.001 and 0.004). Find the interarrival time for which the maximum throughput is achieved. Calculate the offered load that corresponds to this interarrival time. Why does the throughput stop increasing even when the load is increased further?
