| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Information communication networks depend on power delivery from power distribution networks. We therefore evaluate vulnerability of information communication networks when power distribution networks partly/completely stop power supply. We first describe a topology model of the power distribution network in campus buildings from the perspective of power failure domains, and propose the vulnerability of the corresponding information communication network, in which the metric is the bandwidth of system-wide traffic flows. We then evaluate the vulnerability of a campus-wide information communication network. The results indicate that, in the case when all traffic flows concentrate in a data center, the probability of high vulnerability (which blocks all the communications) reaches 0.01 but this is improved by applying UPSs to the servers and their neighbor switches in the data center. On the other hand, in the case when traffic flows are distributed to each room in the campus, the probability is 0.003 but this vulnerability is little improved by applying more than a hundred of UPSs. | |
