What is software-defined networking? Software-defined networking (SDN) is a new technology designed to make your network more agile and centrally controlled. While today’s networks are mostly static, slow to change, and dedicated to single services, SDN gives you the ability to create a network that can handle many different services in a dynamic fashion, allowing you to consolidate multiple services into one common infrastructure. Essentially, an SDN’s network decouples network control and forwarding functions so that networking control becomes programmable, allowing its underlying infrastructure to be abstracted for applications and other network services.
A software-defined network works by virtualizing a network, giving you new levels of visibility and control. Simply put, it moves control of the network away from all of the individual pieces to a centralized dashboard where you are always in the know, where you can build and adapt the perfect transport network in real time. Instead of having to do manual updates, you can program it to adapt dynamically. The rules you set and define help your network become more intelligent and responsive so you can allocate bandwidth automatically, making sure the most important traffic takes priority. By pooling your network capacity, you can make efficient use of all your resources so that staff and customers have a seamless user experience. Because your network knows what's going on, it can detect and block security threats before they have the chance to derail your business.
The main objective of an SDN is to make networks more agile and flexible and to improve network control so that enterprises, as well as service providers, can quickly respond to changing business requirements. Its main goal is to eliminate technology and management silos, allowing organizations to orchestrate services from end to end. With software-defined networking, a lot of step-by-step manual provisioning errors and other issues are reduced, resulting in significantly improved service provisioning compared to old networking approaches.
The three layers of an SDN are made up of:
SDN is important because it provides organizations with increased control, greater speed and flexibility, a customizable network infrastructure, and most importantly, robust security. With an SDN, developers can execute greater control levels over the flow of network traffic by simply programming an open software-based controller. It also lets network administrators have more flexibility when choosing networking equipment, giving them the choice to select a single protocol to use with any number of hardware devices via a central controller.
SDN is also important because it helps organizations prioritize applications that require more availability and also optimize the flow of data throughout a network. Moreover, an SDN provides complete visibility into an entire network, thus giving companies a holistic overview of security threats.
SDN is worthwhile for organizations for the many advantages it has to offer that traditional networking can’t provide.
The different models of SDN include:
