Software Defined Networking (SDN)

Simple Definition for Beginners: Software Defined Networking (SDN) is a technology that allows for centralized management and control of network infrastructure using software-based controllers. Common Use Example: In SDN, network administrators can use a central controller to dynamically configure and manage network resources, such as switches and routers, based on application needs. Technical Definition for Professionals: Software Defined Networking (SDN) is an architecture that separates the control plane from the data plane in networking devices. Key components of SDN include: · Controller: A central software-based controller that manages and configures network devices. · Separation of Control and Data: The control plane, responsible for network management decisions, is decoupled from the data plane, which handles data forwarding. · Programmability: SDN enables programmable network configurations and policies, allowing for automation and agility. · Open APIs: SDN provides open APIs that allow third-party applications and services to interact with the network infrastructure. · Virtualization: SDN can virtualize network resources, making it easier to scale and manage large networks.
