14.4.4 - Software-Defined Networking

These flashcards cover key vocabulary and concepts related to Software-Defined Networking as introduced in the lecture.

Central policy management

A system where a single source manages network operation rules and automates device configurations.

Transport agnostic

The ability of an overlay network to utilize any available forwarding fabric like Ethernet, Wi-Fi, or cellular.

Zero-touch provisioning

An automated configuration process for new nodes that eliminates the need for manual setup by technicians.

Application aware

Nodes that can identify traffic types (voice, video, IoT) and reserve necessary bandwidth accordingly.

Application layer

This layer applies business logic for traffic prioritization and security policies, including segmentation and ACLs.

Infrastructure layer

The layer containing devices that perform traffic forwarding, switching, routing, and enforcing security policies.

Software-defined networking (SDN)

A model that allows automation and efficient provisioning of networks and server instances.

Northbound API

The interface between the application and control layers in the SDN architecture.

Southbound API

The interface between the SDN controller and infrastructure devices.

Management Plane

A plane that interfaces with the operational plane for monitoring traffic conditions and network status.
