Occurrence rate of extreme events and packet arrival rate under control.
In the control parameter space, ntop denotes the number of top-degree hubs whose capacities are augmented and ri is the ratio of the enhanced capacity to the original capacity. The extreme event occurrence rate REE and the packet arrival rate RA in the parameter space are shown, respectively in (a, b). The simulation parameters are the same as in Fig. 2.
