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


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


Barriers to SDN provider adoption

Many large providers have run small-scale SDN pilots, yet they continue to run into barriers when attempting large-scale deployments. In this tip, read about challenges to large-scale SDN deployment. Continue Reading


Realizing SDN controller application potential

The goal of a SDN controller in a typical architecture is to convert a route to related sequence of device-forwarding behavior into specific forwarding changes. Learn the ins-and-outs to unlocking the potential of these controller applications. Continue Reading

Why are providers interested in SDN?

The purchase of network virtualization company Nicira Networks by VMware jump-started provider interest in the SDN market. This blog explores why providers are flocking to the new technology and how SDN can solve operational problems and monetize their networks. Continue Reading


SDN applications for service providers

Although still few and far between, SDN applications have emerged, allowing service providers to streamline services, gain agility and even generate revenue. Read about the ways Google uses OpenFlow, how SDN can improve collaboration and video, and how organizations are interconnecting physical networks and domains using SDN. Additionally, learn how SDN improves security, but how it also poses new concerns.

Granular policy control enabled by SDN security

To some, the concept of SDN sends security red flags, but experts maintain SDN technology is just as likely to enhance network security as it is to pose new challenges. Continue Reading

3NFV basics-

What to know about network functions virtualization

Software-defined networking and network functions virtualization are often complementary to one another, but they're not the same. Learn about the basics of NFV and where it intersects with SDN.


Network functions virtualization takes reigns from hardware

NFV allows engineers to replace traditional network devices with software that lives on commodity servers. It's complementary to SDN, but it's not the same. Discover more benefits of NFV and how it offers flexibility and reduces costs. Continue Reading


Network functions virtualization revolutionizes architecture

NFV aims to move network functions out of network equipment and onto virtual hosting. Read more on how NVF depends on the execution of four steps, as well as management and standard challenges associated with it. Continue Reading


SDN plus NFV means service orchestration in mobile networks

SDN and NVF can address mobile network challenges in two ways: through dynamic resource orchestration and intelligent service orchestration. Continue Reading
