Part I: SDN and NFV
SDN for Communications and Networking
Respond Quickly to Changing Market Requirements
There are scalable Intel®-based platforms for all four layers of
SDN architecture. For high-end networks, Intel Xeon processors
are ideal for the orchestration, network applications and
controller layers, as well as for virtualized switches in the node
layer. Interoperable with virtual switches, Intel supplies the
key components to build a physical switching platform for the
node layer. It is based on the Intel® Ethernet Switch FM6764 for
packet forwarding and an AMC module built with the Intel® Xeon®
processor E5-26xx series for control plane functions.
To remain competitive, today's network operators need to
be able to respond to evolving markets and traffic types in a
timeframe of hours and days rather than the months and years
more typical of traditional carrier grade networks. The latest
Intel® Platform for Communications Infrastructure opens the
door for network service providers to gain unprecedented
flexibility and control over customer offerings through the
use of SDN and NFV. By virtualizing network functions on Intel
architecture, network operators can more easily add workloads,
such as DPI, geographic load balancing and power management,
needed for services and cost reduction – thereby improving the
bottom line. For more details about how to implement the node
layer, see Part II of this series titled, "Implementing SDN AND
NFV with Intel® Architecture."
Intel developed reference designs for physical and virtual
switches, called respectively:
• Intel® Open Network Platform Switch Reference Design
(Intel® ONP Switch Reference Design)
• Intel® Open Network Platform Server Reference Design
(Intel® ONP Server Reference Design)
The high performance and flexibility of these designs is
partly attributable to two key capabilities: accelerated packet
forwarding and a common API between physical and virtual
switches. Exceptional packet forwarding performance has been
demonstrated using the Intel Data Plane Development Kit (Intel
DPDK), a set of libraries whose source code is available for
developers to integrate and/or modify for use in a production
switch. The common API is called Open Networking Software
(ONS), which implements OpenFlow and Open vSwitch, but also
provides many more features that can make networks faster and

Intel® Virtualization Technology (Intel® VT) requires a computer system with an enabled Intel® processor, BIOS, virtual machine monitor (VMM), and for some uses, certain platform software
enabled for it. Functionality, performance, or other benefits will vary depending on hardware and software configurations and may require a BIOS update. Software applications may not be
compatible with all operating systems. Please check with your application vendor.
