NFV and SDN DefinitionsNetwork Functions Virtualization aims to address the issue of having a large and increasing variety of proprietary hardware appliances. Its approach is to leverage standard IT virtualization technology to consolidate many types of network equipment onto industry standard high volume servers, switches and storage.

… In the Software Defined Networking architecture, the control and data planes are decoupled, network intelligence and state are logically centralized and the underlying network infrastructure is abstracted from the applications …

NFV and SDN are mutually beneficial but are not dependent on each other.

Operation in a traditional network environment

4

• The control plane is populated either by routing protocols or by static routes.• The control plane thus adds forwarding state to the data plane. • The data plane makes forwarding decisions based on the state information.• Both the forwarding (or data plane) and the high level routing decisions (control plane) occur on the same

device.

SDN Abstractions

5

“Modularity based on abstraction is the way things get done.”-Barbara Liskov

Data Plane abstractions: OSI Model

Control Plane abstractions: Problem 1: Compatible with low-level hardware / software devicesProblem 2: Need to make decisions based on the entire network topologyProblem 3: Need to configure all switches and routers

Solution 1: Abstraction of the forwarding planeIndustry Standard Openflow Protocol (Flow Tables)

Solution 2: Abstraction of the network state Inform the controller -> Topology Map

Solution 3: Abstraction of the control planeExternal applications can manipulate the network viaAPIs using Java or REST

SDN Hybrid Mode

Hybrid Switch Mode: Some VLANs do OpenFlow, some other VLANs use traditional processing

Hybrid Forwarding Mode: Forwarding decisions will be made by the switches, specific packet types can be overridden
