Next, we compared the results of the coscheduling algorithms in the simulator.

We only give results of the DCS scheme, which is the coscheduling algorithm used in

our distributed Web server model, and the spin block scheme (SB). In this validation,

we also vary the number of applications to show the coscheduling effect. Figure 3.5 (c)

and (d) depict the round trip time comparison between the simulation results and the

real experiments, and these two results are quite similar. These experiments validate the

accuracy of the underlying communication mechanism and coscheduling schemes.
