2. 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

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

7. 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

8. Adaptability and Flexibility
Software Defined Business
 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

9. Compelling Advantages:
Cost
• 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 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

13. 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

 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
