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.

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.
