New Report Delves into the World of Carrier NFV, SDN

By Paula Bernier November 11, 2014

New research from offers a lay of the network functions virtualization and software-defined networking land – providing details on infrastructure provider and telco strategies on this front, an examination of key ecosystems, and a rundown of key standardization efforts.

AT&T, BT, Comcast, DT, KDDI, KPN, Orange, Telecom Italia, Telefonica, and Verizon are among the service providers covered in the “SDN and NFV in a Telco World” report. Service provider ARM’s suppliers addressed in the paper include Akamai, Alcatel-Lucent, Cisco Systems, CDNetworks, Edgecast, Ericsson, LimeLight, JetStream, Juniper Networks, Saguna Networks, and Verivue.

The tier 1 service providers made clear their interest in NFV when they formed an ETSI group and issued their own report outlining the planned move to this new technology, which espouses more software-centric network functionality that can run on industry-standard hardware in an effort to lower costs and enable more flexibility.

These same companies are exploring, and in some cases now beginning to implement SDN in their networks for more agile network management. For example, AT&T recently introduced its Network On Demand SDN, which enables companies to order, add to, and alter their network services on the fly.

NTT Communications previously launched a similar service, under the Arcstar Universal One brand. It rolled out those services in select countries last year, and made it a global offering earlier this year.

In the near term, much of the focus on NFV and SDN was about how to enable carrier cost savings by, for example, simplifying the network, and enabling network operators and their developers to use commercial-off-the-shelf hardware. But in the longer term, it’s about the transformation not only of carrier networks, but also of the basic mindset and business strategies at these carriers. And that involves moving from static networks to a new software-defined networking architecture that is dynamic, and will enable network operators to expedite the delivery of more tailored services.
