NEC Contributes Network Virtualization to OpenDaylight's Hydrogen Release NEC to demonstrate Virtual Tenant Network at OpenDaylight Summit, Feb. 4-5 in Santa Clara, CA

*** For immediate use February 4, 2014

Irving, Texas – February 4, 2014 NEC Corporation of America (NEC), a leading provider and integrator of advanced IT and communications solutions, and a pioneer in OpenFlow-based Software-Defined Networking (SDN), today announced with NEC Corporation in Japan that their Virtual Tenant Network (VTN)  contribution to the OpenDaylight Project is featured in the organization's first release, called "Hydrogen," which was revealed at the first annual OpenDaylight Summit. The OpenDaylight Project is a community-led and industry-supported open source framework to advance Software-Defined Networking (SDN) and Network Functions Virtualization (NFV), and NEC is a founding gold member of the project.

The VTN, introduced by NEC at the July 2013 HackFest, consists of a set of technology components that provide a multi-tenant virtual network through the OpenDaylight controller. Su-Hun Yun, senior manager with NEC Corporation of America, will be presenting a live demo of VTN using multiple OpenDaylight controllers with OpenStack integration during the OpenDaylight Summit in Santa Clara, CA. Yun's summit session is scheduled for Tuesday, Feb. 4, from 1:30-3:20 p.m. PST.

"The VTN is a core technology of NEC's ProgrammbleFlow(R) Network Fabric, and has been deployed globally by carrier and enterprise customers for their production networks," said Don Clark, director of business development for NEC Corporation of America. "The VTN network design enables deployment of logical networks on top of any underlying physical network topology, reducing complexity of traditional network design and increasing service agility. We're pleased to be part of the Hydrogen release."

Traditionally, physical networks have been configured as silos for each department within an organization or for each customer of a service provider. The result is huge, unneeded hardware investments and increased operating expenses because of underutilized, redundant network equipment.

The VTN addresses this issue by providing an abstraction that enables the complete separation of the network's logical plane from its physical plane. In other words, it "hides" the complexity of the physical network and enables users to design and deploy any desired network for their customers, regardless of physical network or underlying operational characteristics. With the VTN, organizations can develop applications to program the network using Northbound APIs. Once the network has been defined using VTN, it will automatically be mapped to the physical network through the controller.

In addition to the advantage of hidden complexity mentioned above, benefits of the VTN include:

  • More efficient management of the network resources
  • Reduced time to configure network services
  • Minimized network configuration errors

"Technical contributions by NEC to OpenDaylight have made it possible for end users to use Hydrogen— the project's first open source software release— to easily evaluate a multi-tenant network solution and compare and contrast it to other models," said Neela Jacques, executive director, OpenDaylight. "Collaborative development taking place within the OpenDaylight community is accelerating the development of software that will enable widespread adoption of SDN and NFV."

The OpenDaylight Summit is a new annual conference designed to provide a collaboration and education space for innovators, developers, and users in the Software-Defined Networking (SDN) and Network Functions Virtualization (NFV) space. The summit brings together the community, projects, products, and companies that are driving the SDN and NFV ecosystems today, along with best practices from the world of traditional open source.


About NEC's ProgrammableFlow Networking Suite
Initially launched in 2011, the ProgrammableFlow networking suite was the first commercially available SDN solution to leverage the OpenFlow protocol enabling complete network virtualization, allowing customers to easily deploy, control, monitor, and manage multi-tenant network infrastructure. As IT organizations seek to improve service delivery and user experience through strategic projects, such as cloud infrastructure and BYOD, the complexity and manual processes of traditional network design can negatively impact the success of these initiatives. ProgrammableFlow transforms network performance and agility by providing production-ready SDN solutions that increase flexibility, visibility and efficiency, while reducing complexity and controlling cost.
