The Rise of the OTTs
OTTs build services on top of commoditized technologies:
Scale Out Compute and Storage Broadcom COTS switches Open Source Software
Scale Up Virtualization Multi-Technology Compute, Storage,
IP, MPLS, Packet-Optical Networks
OTTs are early adopters of SDN and NFV

Commoditization
Custom -> Standard -> White-box -> Bare Metal
Proprietary -> Standard -> Open source -> ‘Free’
OTT Business Models exploit Commoditization

Opportunity for Carriers:Both above and below the Line:
Integration Optical + Packet + Storage + Compute + Software + …
Agility Planning, Operations, PM and Analytics DIY Programmability Integration with Information Technology systems
Virtualization and Delegation of Control Network and VNF as a Service End-User empowerment via APIs

Adaptability and Flexibility Software Defined Business
CYAN CONFIDENTIAL
Today’s Assets = Tomorrow’s liabilities Obsolescence and cost of maintenance Commoditization and revenue erosion Opportunity cost
Adaptability requires Modularity: New Applications New Technologies
Modularity is more of a challenge higher up the stack Paradox: Hardware is more modular than software

Cost
CYAN CONFIDENTIAL
• Software Reuse
• Hardware Virtualization Savings
• Reduction in Design Costs
• Hardware Import Duty (multinational carriers)
• Installation Costs
• Equipment Recovery
• Simplified Project management
• Elimination of site surveys, cabling, etc
• Shipping Costs
• Reduced time to revenue
• Quicker physical deployment
• Quicker service turn-up and change orders
• Elastic services as a Utility
• NFVaaS (firewall, load balancing, encryption..)
• Consistency through automation
• End User configuration
• ICT integration
• Short term, service contracts
• NaaS
• Isolation based security improvements

NFV Driving Network Transformation DC technology is Commoditizing
Application and Content Networks VM and Content Placement
More Data Centers Power Law Size Distribution
Few Hyper Scale DCs Long Tail of Small DCs provide proximity, resilience, low latency,
partition tolerance
NFV and the confluence of WANs/MANs + DCs Multi-layer, multi-vendor WAN/MAN Flexible placement of content, functions and applications
Telco-Cloud orchestration ≡ Integration

ETSI NFV End-to-End Reference Architecture
14
Complies with ETSI’s NFV ISG Management and Orchestration (MANO) framework
Planet Orchestrate serves as the orchestrator and VNF manager, where needed
Supports centralized and distributed NFV deployments
NFVO can stand alone or work in concert with other Planet Orchestrate capabilities
