SDN basics for service providers
In this guide, learn the basics of network functions virtualization, SDN architecture and SDN applications for the service provider network
Introduction
Software-defined networking has caught the eye of service providers. While SDN strategies and use cases are just beginning to emerge, service providers see the potential in using the technology to optimize networks and create revenue-producing services.
Ultimately, service providers are hoping that SDN will enable the long-sought-after goal of application-aware and application-reactive networks. They're also aiming to enable network virtualization for agility and cost savings. To meet those needs, vendors are developing a plethora of SDN products.
However, there's a ways to go before the full potential of SDN will be known.
In this guide to SDN basics and applications for service providers, learn basic SDN and NFV terminology and technology choices, as well as the challenges service providers face when building SDN environments.

SDN basics for service providers
Before providers can use software-defined networking to drive down costs and promote agility, they must first understand the choices in SDN models and strategies. Service providers must choose between three SDN models, and part of that decision will be driven by determining which applications service providers want to run on the SDN controller. Read more on the basic elements of SDN and why providers are flocking to the new technology.
The three models of SDN
Before providers can consider SDN deployment, they must determine which model to support. This expert tip outlines the three SDN models to choose from. Continue Reading
