NTT Communications Leverages SDN to Let Customers Expedite the Creation of Network Overlays

By Paula Bernier December 11, 2013

According to some accounts, software-defined networking is being driven more by telcos’ interests in lowering their operational costs than anything else. But a new move by Japan’s NTT Communications Corp. shows that some carriers are being innovative on this front.

Come March, NTT Communications expects to deliver a new software-defined networking-enabled solution that lets users create and control networks at will over their corporate networks or the Internet. NTT says this offering will be a first in the industry.

This capability requires users to install an application on a PC, smartphone or similar device, or use an adapter. The virtual network creation itself will be done via the NTT Communications Business Portal, a free online site for NTT Communications corporate users that launched Oct. 31.

Arcstar Universal One Virtual Option, as this NTT Communications capability will be know, will come first to Australia, Germany, Hong Kong, Japan, the U.K., and the U.S. The plan is to expand to 30 countries over time.

While we’ve been hearing about customer self-provisioning for some time, and virtual private networks have been around for a few years, what the Arcstar Universal One Virtual Option promises is more customer control, reduced costs (by up to 60 percent) and shorter configuration windows (80 percent faster), as compared with conventional methods that involve a dedicated gateway and reassignment of IP addresses to connect to a common server from a different network environment.

Here’s where SDN comes in, according to NTT Communications. SDN is leveraged to define data flows so customers can divide or integrate network resources – whatever or wherever they are. And NTT’s controller makes the network connections and disconnections via the Business Portal.

NTT has been an evangelist for the SDN movement. As explained in the May issue of TMC’s INTERNET TELEPHONY magazine, NTT’s Enterprise Cloud is an SDN-based virtualized infrastructure-as-a-service offering that is now available via multiple data centers around the world. In June of 2012 the service went live at data centers in Hong Kong and Japan. This February it was added at data centers in California and Virginia, England, and Singapore. And in March it opened data centers in Australia, Malaysia and Thailand.

In June, NTT Com unveiled “the world's first SDN-based cloud migration service, on-premises connection.” It was initially available in Japan and will roll out later to additional locations around the world.
