Figure 8.57
Indirect network compared with two direct networks, using
locality L = 0.25.
For

(32, 2) c = 20.5.
For
d87111c01013bcda00bb8640fdff6754.gif
(10, 3) c = 22.6.
For the waiting time,

For (32, 2) and L = .25, this is:
d87111c01013bcda00bb8640fdff6754.gif
r = 50m.
For (10, 3) and L = .25, this is:
d87111c01013bcda00bb8640fdff6754.gif
r = 29.6m.
Now

We plot Tc + Tw for L = 0.25 and compare to the indirect network in Figure 8.57. Note that for low traffic, the static direct networks give better performance than do the more expensive indirect networks.
