Limitations of SDN and NFV
Monolithic silos for different technology and vendor domains make network transformation complex and inefficient
Disconnected control and orchestration of physical and virtual resources
Duplication of key management functions across multiple domains
Legacy OSS/BSS lacks the self-service programmability to automate services from end-to-end across domains

“Purist” vs. “Pragmatic” Network Virtualization
Considerations along the way• How open is open?• Open source vs. published APIs• Maturing standards• White box vs. traditional networking HW• Virtual vs. Physical Network Functions
All fine, but ultimately, must derive business value to justify the journey• Make money, save money…• Can’t wait for all this to resolve to the
“purist” solution• Triggering us to examine “pragmatic”
solutions• Leading us to orchestration
“Purist” Fully open SW on top ofCommoditized White box HW

Overcoming the Limitations – Orchestration
Multi-domain service orchestration eliminates silos and converges software functions
Abstracts operations regardless of underlying virtual or physical infrastructure
Utilizes the latest software advancements to enable operational scale, efficiency and self-service programmability

Virtualization for Mobility Ecosystems
A range of virtualization models being examined:Cloud RAN – centralized/virtualized BBU
Virtual Cell-Site Routing with potentially additional VNFs (i.e., DPI)
Virtual PE’s at End Office/Central Office or in the Exchanges/Data Centers
vEPC on COTS server hardware
VNF-capable L0-L2 transport devices for network consolidation
Perhaps augmented by centralized, SDN-based routing for L3 simplification
Orchestration will be a key element to pragmatic solutions here
vEPCRadio/
Fronthaul Backhaul Backbone
Potential for Centralized Routing(IP Forwarding only in Network Devices)
L0-L2 Transport

In Summary
Networks for Consumption Built for a different problem statement
Virtualized Networks As with Compute and Store resources, the network must virtualize
SDN/NFV Building Blocks Promising technologies being developed – but it’s a journey
Interconnecting the Cloud Services being delivered by virtualized infrastructure
Orchestration Allows pragmatic steps to network virtualization
API-Based, Open, Modular Mix-and-match software technologies for rapid business impact
