Figure 15 is the average response time (ART) of 5 algorithms in 4 cases. This figure is generated by the average of total requests, not only the selected requests like figure 11 to figure 14. In general, RCBA is the smallest average response time, performs best among the 5 algorithms. In this figure, we can see the characteristics of each algorithm: MaxMin performs well with more requests; FCFS ¡®s ART is increasing by the increment of requests; RoundRobin and MinMin perform not really good at all.
Through 04 cases of different number of requests with the same input, we can see that the distribution of RBCA is quite stable and reasonable. The response time of virtual machines is satisfied compared to other algorithms on the cloud (in the case of few and many requests). |
