Disclaimer: The views expressed in this
presentation are largely those of the presenter,
Influenced by a bunch others who seem to
know a thing or two about this subject…
blah, blah, blah…do not necessarily represent
the views of management etc.

3. 3
Networking undergoing significant shift…
Flexible, virtualized services
Scalable performance
Software and Automation taking key role
Rapid Deployment of New Services,
Quality of Experience Differentiate
Low-power, integrated SoCs
Inflection points:
• S-RAN/C-RAN
• Small cells
• CRAN initiatives
• CoMP etc.
• CDN @ Edge
• Server/Higher performance
compute integration
• Virtualized services
• Compute, Storage & I/O
• SDN (Open Flow, OpenStack,
OpenDaylight…)
• Operator driven initiatives
• NFV
• Goal: Commodity compute with
networking offload.

4. 4
Market dynamics faced by service providers
Market trends
Data explosion accelerates operator profitability problem
Cloud adoption in IT has been very fast and is radically changing the way technology will be
deployed w/ business models that will be adopted by service providers.
Pressure to converge on All-IP, virtualized, commodity platforms in turn puts pressure on the OEM’s
competitive advantage with the highly-optimized proprietary HW platforms they offer today.
Service Provider Value Chain
Top line - growth by addressing new opportunities (OTT revenue stream). Simplified B2B integration
and service differentiation
Bottom line – increased efficiency
Network management simplification in multi-vendor, multi-technology landscape
Business and technology convergence
Result:
Lots of New Entrants
AMAZON, Google, Facebook, Skype,
HP, IBM, Dell, Baidu, Plumgrid, Open Source etc.
ARM – Expansion of engagement strategy
Competitive Landscape Wireless Delivery

5. 5
NFV:Operators’ Cost/Flexibility Analysis
Mobility, IoT driving explosion
of data & devices to manage
Lack of flexibility, agility to
move, re-purpose network
resources
Variety of custom HW growing
Software updates/service
launches take many months
High equipment costs, with
costs ½ every 3.5 years*
Std. Server cost curve ½ every
2 years showing promise*
Cloud/Virtualization
technologies rapidly maturing
for functional consolidation
Availability of OSS frameworks
across networking, storage and
compute
SDN techniques emerging
Seeking a new model to scale network management
Network Function Virtualization group formed (NFV)
Operator Challenges Industry Trends

6. 6
Operators need New Revenue
OTT providers are making the
big margins
Operators cannot compete with
OTT players w/ zero network
cost
Service Providers will likely
need to take more control of the
Services/App provisioning layer
Services Enablement and
Application Integration layer
figure prominently in new
models
This is where the $$$ is.

NextGen Architecture Viewpoint
Key Potential Benefits
Optimum use of network resources
(Lowest cost function)
Increase network agility
Unleash service innovation
Accelerate service “velocity”
Extract business intelligence
Enable dynamic, service-driven
virtual networks “NaaS”
Better economics
Drive down hardware costs
Leverage performance/price advantage
of distributed computing
Lower OPEX

Solutions popping up like dandelions
Conceptual architectures, standards, open source projects
SDN as a Concept/Vision
Centralized Control

VMs, on commodity
servers
Entire network view for
streamlined operations
Network managed by in-
house net IT-merged into
broader infrastructure
Promises Faster, simpler,
cheaper OPEX
NFV: Network Function
Virtualization
Working group under ETSI
Formed by mobile operators
Use SDN concepts- Goal:
virtualize mobile network
elements as possible
Open Flow Project
By Open Networking Forum
All major players in
Defines architecture and API
spec for SDN Controller.
Define protocol commands to
data plane: Narrow focus
OpenDaylight
Many major players from ONF
and the broader industry
Broad Focus: Builds around
OpenFlow (options), filling
gaps such as Services Layer
Open Source Project
OpenStack
This is an Open Source project for
building the next gen Cloud
Infrastructure.
This seems what most will use as
a code base for the back-end
converged infrastructure.

NFV: Operator Perspective/Vision

10. 10
Ecosystem Impact: Incumbent OEMs
Infrastructure incumbents have been responding to trends
Smart, cloud-enabled access equipment, CDN, etc.
Joining many of the initiatives to influence, contribute and
navigate the shift
Most are acquiring/developing SDN software assets to
bolster their readiness and positioning
Prediction: Incumbent OEMs will continue to factor heavily in
solution supply chain
Experience/expertise in system integration/deployment, reliability etc.
The architecture, packaging and value proposition must adapt

11. 11
Ecosystem Impact: Software
Legacy embedded networking ecosystem facing new
entrants from enterprise ecosystem Disruption!
Mostly Proprietary
OEM Code

12. 12
What does this mean for Linaro?
Cloud Orchestration
Compute Networking Storage
LNG: Common Data Plane Programming Model:
Data Plane Optimizations
Optimized SoCs
OpenStack gaining broad adoption
Great opportunity for collaboration
OpenFlow, OpenDaylight Unproven:
Strong concepts, troubling concerns:
Alternatives will no doubt emerge
Lots of opportunity for innovation
& collaboration:
• Hypervisors
• Network virtualization
• HW assist/Open Source HW
• Service/Application Enablement

ARM’s Value Proposition in NFV/SDN
ARM and
Partners
driving
innovation
Not only power but
integration and workload
optimization, and true
commodity,
not monopoly
Common ISA, with
choice, faster innovation
cadence and
Unmatched range of
innovative SoC solutions
Open source

disruption
ARM, Linaro and
Partners investing in
Open Source
Many Open Source
Projects opening up
Opportunity or
innovation, collaboration
& disruption never
higher.
ARM
