This document discusses networking concepts in HP Helion, including SDN and NFV. It aims to leverage standard virtualization technology to consolidate network equipment onto industry standard servers. SDN decouples the control plane and data plane, logically centralizing network intelligence. The document also discusses how SDN and NFV can work together but are not dependent on each other, and provides examples of SDN implementations including hybrid modes and HP Helion's use of SDN.

NFV and SDN Definitions
Network 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 devices
Problem 2: Need to make decisions based on the entire network
topology
Problem 3: Need to configure all switches and routers
Solution 1: Abstraction of the forwarding plane
Industry Standard Openflow Protocol (Flow
Tables)
Solution 2: Abstraction of the network state
Inform the controller -> Topology Map
Solution 3: Abstraction of the control plane
External applications can manipulate the network
via
APIs using Java or REST

SDN Hybrid Mode
6
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
