Distributed metro data centers: – Cloud pushing closer to the customer as distributed caching
systems pushed closer to the edge (e.g., Netflix caching)
– 85% of all traffic is projected to stay within the metro
– Cloud-based applications emerging to consume higher
bandwidth (e.g., 4K HDTV, 4K HD gaming, biz services, etc.)

Drivers and Enablers
• What do providers want? - Service agility & automation- User-enabled services- Intelligent networks- Lower opex and capex
• How do operators get what they want?- Transition to open, software-centric networks- Real-time network programmability
• Key technology enablers- Software defined networking (SDN) for end-
to-end network programmability and optimization of networking devices
- Network functions virtualization (NFV) moves hardware-centric functions into software that can run on general compute infrastructure

Agility & Data Center Architectures
Transition to software-centric networks
– Virtualization used whenever possible by
moving functions out of purpose-built
hardware and into general compute resources
– Functions available via App Store model
Service orchestration
– Physical and virtual resources allocated real-
time through orchestration systems
– Flexible APIs required
– User-enabled services via portals
Service providers transitioning to agile
models
– Embracing of Agile and DevOps development
principles
– Rapid release cycles for service flexibility
Open networks
– Multi-vendor software functions
– Programmable networks through open APIs

Open-Sourced Software
“Standards efforts take time and products built on standards take longer to reach
the market. Open Source software offers the opportunity to accelerate
deployment timeframes and the standards development process.”
Source: NFV Open Platform Formation Discussion
“In 2007, 80% of those surveyed by Gartner cited cost as the primary driver of
their open source use. Today [2014], 80% of those surveyed cite the "high
quality“ of open source as the primary reason for using it.”
Source: http://readwrite.com/2014/04/07/open‐source‐software‐cost-recruiting‐participation
“One of the benefits we [PayPal] see in an open development model is leveraging
the intellectual mindset of people who are outside of our company - across the
world - who have this passion.”

SDN & NFV are independent technologies that may or may not be used
together, but maximize value when deployed together
SDN & NFV Relationship

IP Forwarding: All network elements exchange routing
information across the data plane via dynamic routing
protocols (RIP, OSPF, BGP, IS-IS, etc) and make
forwarding decisions on a per-hop basis.

Protocols
Early Days of Core IP Networks

MPLS Switching: IP lookups performed at the edge, switching
in the core. Introduced optional control and data plane
separation, but control plane still used mix of dynamic protocols
(LDP, I-BGP, OSPF-TE, etc).

SDN ControllerControls how all network elements forward packets. Provides centralized,
abstracted view of the overall network. Runs in high-compute data center.
Data Plane
Control Plane
Open APIs for config (e.g.,
NETCONF) and forwarding
(e.g. OpenFlow)

applications – QoS monitoring, PM reporting, etc.)
Network Orchestration(coordinates and controls allocation of all
network resources)

Flexibility to introduce new services, reconfigure based on global
policy; Global visibility; Reduced OPEX

Benefits
• Centralizes VNFs in the cloud
• Increases provider agility and by
enabling expansion of business
services through service chaining
• Lowest cost solution for

Infrastructure
Benefits
• Open architecture supports VNFs from
multiple vendors on premises
Cloud Extension Appliance
• Bolsters cloud service offerings by
providing on-premises compute and
storage resources
• Maximum Flexibility – deploy VNFs
and applications in the optimal location

Combining SDN and NFV

SDN and NFV are game changing technologies that have already begun to alter our perspective on network and service design
These technologies, combined with automation and orchestration, will allow service providers to become more agile, to differentiate and will enable them to compete in our cloud culture
Software Defined Access Networks, distributed compute resources and virtualized network functions will allow providers to dynamically grow, alter and manage the network and the cloud
ADTRAN will continue to provide industry leadership and innovation while continuing to endorse open and standards-based next generation networks
