 Part 3 and 4 shows the detailed power consumption and utilization level of each host or switch. 
 For Host #0, it consumed 29,653 Wh which hosted 4 VMs at the time 0. From the time 0 until 2390, the host utilized 51200 MIPS. 
 For Switch #103, it consumed 27,511 Wh for the whole experiment. No traffic was occurred until the time 22660, and 2 ports were active between 22660 and 90180 seconds.
