NICT builds and operates JGN-X, research and development testbed network towards establishment of the New Generation network.
In this experiment, in accordance with current situation of many SDN technologies proposed, NICT used 10 different SDN technologies in parallel conditions, to actualize flexible selection system of necessary network services.
The contents (HD video from Sapporo Snow Festival venue) had been transmitted to multiple points within Japan and abroad, in high quality video image of HD to 4K. With this, NICT tested network operational technology in wide-area with various functions. Considering advanced operation in the new generation, NICT also measured and analyzed the network status in coordination with SDN controllers.
Also, in collaboration with research organizations in Singapore and Philippine, VOD and 4K live streaming experiment was also performed using LIME, an ITU-T Standard IPTV technology. Moreover, in Sapporo Snow Festival venue, we conducted a video transmission experiment of area-limited Wi-Fi and Area One Seg broadcasting for iPhone/Android smartphones, and experiment of 100Gbps ultra-speed to transmit a video image between the venue and JGN-X. Those experiments were based on experiment plans in the appendix, in cooperation and collaboration with organizations shown in the exhibit.
