Software Network Solutions (SDN, SDWAN, SDLAN)
The software-defined network (SDN) allows the network control plane to physically separate from the propulsion plane, and a control plane to control various devices. The software-defined network (SDN) is a new architecture that is dynamic, manageable, affordable, adaptable, and makes it ideal for the high bandwidth and dynamic nature of today's applications. This architecture separates network control and routing functions that allow network control to be programmed directly and the infrastructure to be abstracted for applications and network services.
Software Defined Network (SDN) Architecture
Programmable directly: Network control can be programmed directly because it is separated from the routing functions.
Agile: The architecture offers routing control, allowing administrators to dynamically adjust the flow of traffic across the network to meet changing needs.
Centrally managed: Network intelligence is centralized (logically) on software-based SDN controllers that maintain an overview of the networks. This sees applications and policy engines as one logical key.
Programmatically configured: SDN enables network administrators to configure, manage, secure and optimize network resources through dynamic, automated SDN programs; because these programs are not dependent on proprietary software, they can write themselves.
Open standards - Vendor Based - Neutral: SDN simplifies network design and operation when implemented through open standards because instructions are provided by SDN controllers rather than multiple vendor specific devices and protocols.
