March 18, 2013

The National Institute of Information and Communications Technology (NICT, President: Dr. Hideo Miyahara) is promoting various kinds of network technologies over JGN-X toward the New Generation. In this experiment, NICT implemented 10 different Software Defined Networks (SDN) in parallel conditions, and successfully transmitted broadcast video of the Sapporo Snow Festival. This realized high resolution video streaming over dynamic on-demand network which enabled speedy change in function to meet user requirement, with embedded function of network analysis/monitoring.

This success will contribute to fundamental technologies of new network service, which makes it possible to select the most suitable network for its use (e.g. high resolution movies, or remote conference systems ) in on-demand basis.

Background and overview

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.

Points in experiment

  • 10 different SDNs(Software Defined Network)selected/switched by user side
  • Traffic analysis in coordination with network controller, developed for SDN era.
  • Collaboration of industry, government and academia, focusing on demonstrative experiment of new network technology and cutting-edge products(e.g. 100GE, 4K) with over 50 organizations from within Japan and abroad.

Future prospects

By accumulating on-demand SDN network technology and its operational intelligence, we believe we can connect to new generation network of the future which can quickly deliver various functions and quality that meets user demands.

A new network testbed environment to achieve new generation network technology and deployment. NICT has been operating JGN-X since April, 2011.

Sapporo Snow Festival

The event started in 1950 from 6 snow statues put in the Odori Park by local junior and high school students. Attracting more than 2 million visitors during the event every year, it keeps growing and being loved by people from all over the world. The 64th Sapporo Snow Festival was held from Feb. 5th(Tue) through 11th(Mon).


A generic name of network technologies and control plane interface specifications, proposed by “Open Flow Consosium” (, originally led by Stanford University in US. Marked one of SDN(Software Defined Network)technologies which is to define how network controlled by software. Currently they are working toward standarization in the industry in Open Networking Foundation (ONF) ( The latest specification is v1.3.


High quality TV standard for next generation. It is expected the service will start in summer of 2014. With 8 million pixels, which are 4 times larger than current Full HD, it realizes very high quality in videos. First commercial product was from Toshiba in December 2011.

High resolution network measurement technology(PRESTA 10G)

PRESTA 10G was used for the analysis. It is a network measurement system enabling 10-nano level measurement with 10Gbps capturing/generating functions. It is developed by NTT Network Innovation Laboratory and NTT-IT, and currently also cooperated by Kanagawa Institute of Technology in wide-area experiments.


Lightweight Interactive Multimedia Environment for IPTV services (LIME) is a world-standard of IPTV for TV streaming on the Internet as well as other delivery networks. As a multimedia framework, it was discussed in IPTV-Global Standards Initiative of ITU-T (International Telecommunication Union), and standardized as Recommendation ITU-T H.762. It is profiled to be used on resource-limited devices like TV-sets and is agnostic as to the digital broadcasting layer, which makes it a general and international common specification.
