Software-defined Networking

Separation of forwarding and control planes A standard, vendor-agnostic interface to program

network hardware Centralized control plane or NOS opened via an

API to application developers Virtualization where multiple NOSs can control

slice of the same hardware device SDN approaches

Underlay (OpenFlow, BGP, PCE-P)

Overlay (VXLAN, MPLS, Segment Routing)


SDN Protocols for Internet and CarrierE Network Programmability


SDN Deployment with OpenFlow

Defined by Open Networking Foundation OpenFlow is an open API that provides a

common instruction set for interacting with packet-forwarding hardware

It is a centralized Controller that separates Data Plane from Control Plane

A single Controller interacts with many switches and allows for quick, dynamic changes as network needs evolve
