Figure 5.14 shows the relationship between Rmax and Emax calculated from
Eqs. (5.1), (5.2), (5.4), (5.5), (5.6), and (5.7). As seen in Fig. 5.14, DRR using
Multiple Queue Report Set can achieve high efficiency together with short
round-robin cycle.
In summary, we have given a DBA example which meets the three perform-
ance requirements mentioned in Sect. 5.2.3:
A. Fairness: Allocates the bandwidth among the users fairly.
B. Low delay: Can bound the maximum delay time within a designed value.
C. High efficiency: Can increase the efficiency of the bandwidth and in-
crease the peak rate as much as possible.
