NEC announced that it trialed a system to dynamically create and utilize optimized networks by monitoring network traffic volumes and information tied to Internet of Things (IoT) devices, such as video cameras.

This trial was conducted in a joint effort with Japan's National Institute of Information and Communications Technology (NICT) using broadcast video images of a Japanese pro-baseball training camp, and utilizing the JGN and RISE testbeds provided by NICT.

For the trial, NEC used a network environment comprising of NICT-owned VPN routers, SDN controllers and SDN switches positioned in Tokyo and Okinawa. NEC provided an IoT service enabler for this network environment.

During the trial, NEC siad it carried out real-time monitoring of network traffic to build and deploy individual virtual networks with the necessary performance capabilities, such as transmission bandwidth and processing capabilities, for successfully transmitting pro-baseball training camp broadcast images from Okinawa, Japan.

Kazumasa Kobayashi, Director of the JGN Network Operatio Group
From the perspectives of cost and operability, it is not realistically feasible to construct individual, independent network infrastructures on a service-by-service basis. Linking IoT service enablers with SDNs is one new solution that enables us to resolve these kinds of issues; and to construct service-oriented networks as needed in order to cater to continually changing IoT environments and requirements.

Shigeru Okuya, GM, SDN/NFV Division, NEC 
Moving forward, we will continue to engage proactively in trials, research and development efforts utilizing SDNs and IoT service enablers in order to improve service quality for telecommunications operators and reduce network operating costs.
