Hitachi Metals to Get into Full Swing Its Joint Technical Development with NTT DATA
-Joint Development of OpenFlow 1.3-Compatible SDN Solutions for Telecommunications Carriers-


Hitachi Metals, Ltd.
NTT DATA Corporation


Hitachi Metals, Ltd. (headquarters: Minato-ku, Tokyo; Chairman and CEO: Kazuyuki Konishi; hereinafter referred to as "Hitachi Metals"), and NTT DATA Corporation (headquarters: Koto-ku, Tokyo; President and CEO: Toshio Iwamoto; hereinafter referred to as "NTT DATA") are scheduled on May 20 to get into full swing their joint technical development of SDN solutions for telecommunications carriers that will realize the integration and unified administration of multiple networks, on the basis of the combination of Hitachi Metals's APRESIA®*1 Ethernet*2 switches and NTT DATA's Virtual Network Controller SDN*3 controller.
The two companies commenced their joint research on SDN solutions for telecommunications carriers in 2013 and have conducted joint verification together with major telecommunications carriers. Utilizing the expertise they obtained through those activities, they have now decided to get into full swing the technical development to create SDN solutions that can be more valuable for telecommunications carriers.
Hitachi Metals and NTT DATA are aiming to complete the development of the solutions and introduce them into commercial networks by 2015.

Telecommunications carriers nowadays are offering wide-ranging services, including VPN (Virtual Private Network) services designed for establishing private networks in a virtual manner, LTE*4 large-capacity mobile broadband communications services, and cloud services. Providing such a wide variety of services, however, requires telecommunications carriers to configure and operate different networks on a service-by-service basis. The resulting increases in capital investment involved in every creation of a new service and the costs required for operations and maintenance have become major challenges for the companies.
Recently, SDN, which can realize the integration and unified administration of multiple networks, has become a focus of attention as a technique to overcome such circumstances. While Hitachi Metals has provided the APRESIA series of Ethernet switches to telecommunications carriers, NTT DATA has marketed their SDN controller, Virtual Network Controller, since 2011. The two companies commenced their joint research on SDN in 2013 and have conducted joint verification together with major telecommunications carriers. Utilizing the expertise they obtained through those activities, they have now decided to get into full swing the technical development to create SDN solutions that can solve the challenges telecommunications carriers are facing today.

SDN solutions featuring the following advantages are to be developed by utilizing Hitachi Metals's APRESIA and NTT DATA's Virtual Network Controller in combination.


Advantages of the solutions to be developed:

  • An integrated network can be configured by accommodating multiple services in the same network and controlling and managing them from an SDN controller in a unified way, which will also contribute to the reduction of costs for capital investment as well as operations and maintenance.
  • An integrated network is configured with services that are assigned with an identifier suited to the traffic characteristics by detecting flows of individual services on the basis of OpenFlow*5 1.3. In this version, large numbers of functions for telecommunications carriers such as PBB*6 and MPLS,*7 which are techniques used for configuring telecommunications carrier networks, have been incorporated.

Advantages of Hitachi Metals's APRESIA (currently applicable to the Apresia 26000 and Apresia 12000 series)

  • OpenFlow 1.3 has been implemented on 100G Ethernet switches for telecommunications-carrier use.
  • Many different APIs*8 (including OpenFlow 1.3) have been prepared to improve compatibility with all kinds of controllers.
  • A hybrid controlling method has been adopted, in which SDN-based centralized control and autonomous distributed control based on conventional switching functions are used in combination.
  • High-speed failure detection and recovery, burst frame*9 detection, different types of counters used for measuring, for example, transmitted/received packets and discarded packets, and many other different features have been incorporated to realize telecommunications-carrier-grade products.

Advantages of NTT DATA's Virtual Network Controller

  • Fully compatible with OpenFlow 1.3 including telecommunications standards used in carrier networks
  • High-quality software applicable to carrier-scale networks, featuring high subscriber ratio and scalable architecture
  • Many different OpenFlow 1.3-compatible switches are supported, including OSS*10 software switches.

Hitachi Metals and NTT DATA are aiming to introduce the solutions into commercial networks by 2015.
