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 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
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.
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.
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
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 and NVF can address mobile network challenges in two ways: through dynamic resource orchestration and intelligent service orchestration. Continue Reading
SDN and network functions virtualization often work together and according to this expert answer, can cause a networking revolution. Continue Reading
