Researchers from NTT DoCoMo, Tohoku University, NEC, Hitachi East Japan Solutions and Fujitsu have set up a joint test bed to examine network resiliency issues during major disasters such as the Great East Japan Earthquake. The test environment has been set-up in the Yokosuka Research Park and at Tohoku University.
The idea is to enable more dynamic network control for dealing with priority mail and voice calls when congestion spikes above a certain threshold.
