Nippon Telegraph and Telephone Corp. (NTT) has developed a technology that enables on-demand transmission of gigabit-class wideband video. NTT verified their achievement in a wide-area experiment in cooperation with National Institute of Information and Communications Technology (NICT).

Users can achieve steady transmission of high-density video such as HDTV by acquiring a path in the network whenever it is needed, without allocating additional network resources or re-optimizing the provisioned network resources.

The experiment was carried out using GEMnet2 and JGN2plus, the R&D testbed networks provided by NTT and NICT, respectively.
