1 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

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

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
