NFV & SDN Zone Week in Review: AT&T, Other Service Providers Move Forward with SDN

By Paula Bernier September 27, 2014

The biggest news on the SDN frontier in the past few days is AT&T’s pronouncement that it will go commercial with its Network On Demand SDN solution starting this year.

AT&T Network On Demand SDN will enable companies to order, add, and alter their own network services on the fly. The carrier has been piloting the service at the University of Texas at Austin since June. The service will launch commercially in Austin later this year, and AT&T intends to expand the rollout to select U.S. markets next year.

This offering sounds similar to what NTT Communications Group is offering under the Arcstar Universal One brand. NTT took this service global earlier this year, having initially launched it in a handful of countries (including the U.S.) last year.

These are, of course, just two of several service providers that have embraced SDN to enable new and improved business models.

Another example on this front is Czech Republic-based cloud computing company tcp cloud, which earlier this week revealed that it is using Juniper networks’ Contrail controller to automate and do orchestration of its network, which includes physical and virtual network elements and embraces the software-defined network vision.

Meanwhile, Tampa-based colocation service provider vXchnge is talking about how it utilizes the software-defined approach to offer “localized” infrastructure to its service, network, cloud and content provider customers.

In other developments related to the move to more software-based networking solutions, workspace company Citrix this week revealed what it described as a strategy shift, saying it will be focusing on software-defined workplace solutions going forward.

Saisei is another company working to improve network efficiency and agility.

The two-year-old company is now pushing its message that current networks are leaving too much of their bandwidth idle but can now use Saisei appliances to run at or near full capacity.  The first release of Saisei’s solutions, which is scheduled to start shipping in about four weeks, will be available as physical or virtual appliances and can run in legacy or SDN-based environments.
