Software Defined Networking (SDN) is an approach to using open protocols to execute globally aware software control at the end of the network to access network switches and routers that typically do use closed firmware.
SDN enables the network to be intelligently controlled using software applications. This helps network operators manage the entire network consistently, without bothering the underlying network technology.
Software Defined Networking: The Benefits
SDN has so many benefits to offer like automated load balancing, on-demand provisioning, streamlined physical infrastructure and the capability to scale network resources in lockstep with application and data needs.
SDN: The Evolution of the NetworksSDN helps the programming of network behavior in a centrally controlled manner through software applications by using APIs. By implementing a common SDN control layer, the network operators can manage the entire network and its devices consistently, regardless of the complexity of the underlying network technology.
The Critical Areas where SDN technology can make a difference:
- Network programmability feature: SDN helps network behavior to be controlled and maintained by the software which resides beyond the networking devices. Hence, network operators can easily tailor the behavior of their networks to accommodate new services.
- Logically centralized intelligence and network control: SDN enables intelligent control and smart management of network resources. With centralized control, bandwidth management, data restoration, network security, and policies can be highly intelligent and well optimized.
