SDN Zone Week in Review

By Erin Harrison April 20, 2013

Several interesting stories came out of the software-defined network (SDN) sector this week. Software-defined networking is an approach to networking in which control is separated from the physical hardware and given to a software application.

Here are some of the major stories as reported by SDN Zone.

NTT Communications has been an early adopter of SDN with the launch of its Enterprise Cloud, a service targeted at multinational organizations looking for highly flexible compute and other data center resources and capabilities.

Enterprise Cloud, an SDN-based virtualized Infrastructure-as-a-Service (IaaS) offering, 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. Last month, it opened data centers in Australia, Malaysia and Thailand.

Add Intel to the growing list of technology companies that hope to successfully redefine their business models in the fast-approaching “post-PC” era. The chipmaker recently announced a new networking strategy centered on SDN and network function virtualization.

These reference architectures, focused on the telecommunications, cloud data center and enterprise data center infrastructure market segments, combine open standards for SDN and NFV with Intel hardware and software, in an effort to allow networks to be more agile and intelligent so they can adapt to changing market dynamics.

Intel’s philosophy is that integrating SDN and NFV on standard x86 platforms help to lower the acquisition and management costs, as well as allow for new innovative services that were not possible before in networking infrastructure, according to Rose Schooler, vice president of Intel Architecture Group and general manager of Intel’s Communications and Storage Infrastructure Group.

In other SDN news, Dell said it will offer its customers a new SDN fabric for data centers. It is being billed as offering lower costs and it is quicker than other options. The suite can also be used at virtual, converged or private cloud settings.

The fabrics include active fabric solutions for SDN-enabled designs, next-generation management software (Dell Active Fabric Manager), and the Dell Networking S5000 modular LAN/SAN switching platform.

The products come in response to recent changes in technology.

“The data center network market has been transformed with new architectures, new technologies and vendors specifically targeting solutions to address the changing size and density of the data center, shifts in traffic patterns, and the increasing requirement to simplify network operations,” Gartner said in a recent report quoted by SDNzone.
