Initially launched as an enterprise do-it-yourself (DIY) appliance play with the potential to cannibalize existing MPLS revenues, software-defined wide-area network (SD-WAN) has rapidly become a managed services offering – one that any provider hoping to serve the business market must have in its portfolio. That includes traditional telecom network opera- tors, cloud providers, managed service providers and cable operators.
Service providers across the board are trying to understand how to succeed in this promising new area. But what are the tools and technologies needed to succeed?
This white paper takes an in-depth look at the emerging SD-WAN market from the service provider perspective. The paper outlines the drivers for SD-WAN, details the benefits of offering SD-WANs for service providers and charts a realistic course for the evolution of SD-WANs in the era of virtualization and network functions virtualization (NFV).
