NTT Comms Uses SDN for Global Virtual Network Service

TOKYO -- NTT Communications Corporation (NTT Com), the data, cloud and international communications business within NTT (NYSE: NTT), announced today the planned March 2014 launch of Arcstar Universal One Virtual Option which will allow users to easily create, use and control overlay networks on-demand via existing corporate networks or the Internet using software-defined network (SDN) virtual technology. NTT Com will be the first carrier to offer such a service.

Arcstar Universal One Virtual Option initially will be available in 21 countries, including Japan, the US, Singapore, the UK, Hong Kong, Germany and Australia, eventually expanding to 30 countries. Reservations will be accepted from in March 2014.

One or more flexible, secure, low-cost, on-demand networks can be created simply by installing an application on a PC, smartphone or similar device, or by using an adapter. Since the user will remain in their existing network environment, there will be no need to change IP addresses.

Integrated management and operation of newly created virtual networks will be possible using the NTT Communications Business Portal, which greatly reduces the time to add or change network configurations. The portal, a free online site for NTT Com corporate users, was launched on October 31.

Arcstar Universal One Virtual Option is a highly efficient service. In the case of a business consolidation or intercompany project, for example, the customer can expect to reduce costs by up to 60% and shorten the configuration period by up 80% compared to the conventional establishment of a dedicated gateway and reassignment of IP addresses to connect to a common server from a different network environment (NTT Com estimates based on integrating 100 locations with two virtual private networks and overlapping IP addresses).

The configuration period can be shortened by 50% in the case of integrating smaller bases, or setting up a base outside Japan with a secure network connection (NTT Com estimates based on a secure network for 30 locations via Internet access).

SDN architecture is used to define data flows in a network, enabling the customer to divide or integrate a network’s pooled resources regardless of its physical configuration. NTT Com’s original network virtualization technology securely encrypts communication on the overlay network. NTT Com also developed the controller function to freely connect to or disconnect from the network via the Business Portal.

The service application will be free to download and will cost just JPY 250 per month to use. The dedicated adapter will cost JPY 15,000 and JPY 1,500 per month to use (prices exclude 5% consumption tax, which will change to 8% from April 1, 2014).
