Verizon announced it is "transforming its network by implementing a software defined network architecture, laying the groundwork for new innovative services and applications. This SDN-based architecture is designed to introduce new operational efficiencies and allow for the enablement of rapid and flexible service delivery to Verizon’s customers.
.. To enable its network vision, Verizon and its technology vendors have co-authored a comprehensive SDN network architecture document, which includes all interface specifications and reference architectures plus requirements for both the control layer and forwarding box functions. This network architecture document will enable Verizon’s key technology partners to develop solutions to achieve the business and technical benefits of an SDN-enabled network.
Much of the foundational work required to deliver on Verizon’s next-generation network has been underway for several years. Verizon has created live lab environments in San Jose, California; Tampa, Florida; and Waltham, Massachusetts, and has commercial data center environments on both the East and West Coasts".
