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.

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

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 managementNetwork Function Virtualization group formed (NFV)

Operator Challenges Industry Trends

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 Plane in Software, In 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 ETSIFormed by mobile operators

Use SDN concepts- Goal: virtualize mobile network elements as possible

Open Flow ProjectBy Open Networking Forum

All major players in

Defines architecture and API spec for SDN Controller.

Define protocol commands to data plane: Narrow focus

OpenDaylightMany 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.

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

Ecosystem Impact: Software

� Legacy embedded networking ecosystem facing new entrants from enterprise ecosystem Disruption!

Mostly Proprietary OEM Code

What does this mean for Linaro?

Cloud Orchestration

Compute Networking Storage

LNG: Common Data Plane Programming Model:Data Plane OptimizationsOptimized SoCs

OpenStack gaining broad adoptionGreat 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
