Broadcasting Operation Experiment over Multiple SDN Switching Network Succeeds in “Sapporo Snow Festival”

• 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.

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.

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” （http://www.openflowswitch.org/）, 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) （http://www.opennetworking.org/）. 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.

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.
