This document discusses how network virtualization through NFV (network functions virtualization) can benefit rural broadband providers. NFV allows software-based virtual network functions (VNFs) to replace expensive proprietary hardware, reducing costs through operational efficiencies. It provides rural providers flexibility to innovate, quickly launch new revenue-generating services, and customize the end-user experience. NFV also offers a pay-as-you-grow model through software licensing that minimizes upfront investment risks. The document argues NFV can help rural providers compete through lower prices, while gaining agility to adapt networks as needs change over time.

Network Virtualization in Rural Broadband

6. © 2016 ADVA Optical Networking. All rights reserved. Confidential.6
Future of Rural Broadband
• Rural broadband providers face an uncertain future of federal
funding
• Changes in Universal Service Funding make it difficult to obtain funding or
recoup high costs of servicing low-density, remote locations
• Rural broadband providers need new technologies and
strategies to build revenue, reduce costs and gain operational
efficiencies
• Rural broadband providers need strategies for competing and
partnering with larger providers and/or public-owned providers
• Network virtualization provides many advantages for
communication service providers and it can be particularly
beneficial for rural broadband providers

Network Virtualization = Greater Profitability
• Virtualization replaces today’s expensive custom hardware
appliances with software-based virtual network functions
(VNFs) running on low-cost and open commercial off-the-shelf
servers
• Network functions virtualization (NFV) and software defined
networking (SDN) provides service agility, network flexibility
and performance
• To reap the true rewards of NFV and SDN, rural broadband
provides need to focus on pure-play NFV and SDN architectures
• NFV can help rural broadband providers drive new business
today and set them up for continuous innovation in the future

8. © 2016 ADVA Optical Networking. All rights reserved. Confidential.8
What Can You Do With NFV?
• Compete with larger communications providers in neighboring
urban areas
• Automation of network and service operations provide significant reduction
in costs and an opportunity to be more competitive on price
• Quickly define and deploy new services while eliminating the
need for truck rolls and hands-on access to configure remote
network equipment
• Including cloud-based managed services such as security, firewall, VPN,
database, PBX, etc.
• Personalize end-customer experience through granular network
orchestration and management
• License software on a pay-as-you-go or pay-as-you-grow scale
• Eliminate need for huge upfront investment
• Minimize financing on upgrades or expansion

What is Pure-Play Virtualization?
Pure-play virtualization enables users to realize the benefits of the
cloud by replacing closed appliances with their choice of
software that can be hosted anywhere in the network on their
choice of open hardware.

Our Approach to Pure-Play Virtualization
To be considered pure-play virtualization, a solution must
incorporate the following four components:
1. Completely open architecture
• Including hardware and software
2. Open carrier-class orchestration
• Supports a variety of VNFs with internal or external VNFM
3. Comprehensive ecosystem of VNFs
• Both 3rd party and open source
4. High-performance virtual switching and Carrier Ethernet
• Enables single-box deployment anywhere in network

Primed for Innovation
“Our rural broadband clients are a passionate, motivated group and they
will innovate. We’re going to be challenging them to find new and better
ways of providing services with NFV. We fully expect these Tier 3
providers will create new ways to complete on service level and price
without a lot of investment.”
Tory Richtmyer, Mid-State
Consultants

Challenges With NFV
• Current hardware-centric culture and staff skill set
• Training and some staff augmentation to become Agile/DevOps
• Overhead is reduced as new technology facilitates more remote
support and maintenance
• Engineering and support services providers will adapt by adding
software techs and keeping them trained on the newest offerings
• Fear of expense and unknown
• New software licensing schemes and lower-cost hardware reduces
risk
• Partnering with engineering firms and vendors is critical
• Overture Total Cost of Ownership Calculator and Agility Model
• Vetted with service providers of all sizes and areas
• Provides a solid estimate of savings and new service revenue

Summary
• NFV brings real benefits to rural broadband providers
• Operational efficiencies and savings
• New service innovation to grow revenue
• Flexibility for quick and cost-effective changes
• New pay-as-you-go licensing models lessening financial risk for
upgrades and expansion
• Lower overhead costs with fewer truck rolls and “zero-touch” activation,
upgrades and maintenance
• Choice of software. Choice of hardware. Choice of location. Choice to
change.
