SDN and NFV: A Secular Trend

Software-
Defined
Networking
Agility.
Manageability.
Programmability.
 New business models and
revenue opportunities
 Minimize complexity and
network management
 Lower capital and operational
expenses

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
