In Experiment 3, the random DCN/OTN pairs were generated with both
containing the same number of nodes. The network size (i.e., sizes
of both the OTN and the DCN) were doubled for every run and the
restoration time for all possible paths was measured for each of the
four schemes. The pure-random model was used for generating edges with
edge probabilities set to 0.4 and 0.18 for the OTN and DCN respectively.
Figure 9 shows the results of Experiment 3. It shows
the performance of each of the four schemes for varying network size
with information about the number of links in the OTN and DCN (scaled
down ten-fold) in the OTN/DCN graphs on which measurements were performed.
As seen in Figure 9, parallel OBS activation scheme
exhibits the best performance as network size increases, followed by
plain parallel activation.
