“Pragmatic Network Virtualization”?Did you know you needed it?

Me E-Tailing/E-Consuming…

Me Watching Me…

Me Collaborating Online…

A Range of Consumption Models…

…which the Cloud makes possible

Me Consuming in General…

VIRTUALIZED COMPUTE and

STORE

“And now VIRTUALIZED CONNECT!”

But what does that really mean?...

Where Are We Today?

2012-2014

Focus on infrastructure

PoCs and trials to explore and analyze key concepts

Today

Focus on services and revenue models

Production deployments to verify the business case

Tomorrow

Focus on differentiation

Innovative and agile services

Network and Business Transformation

Parallels the Evolution to Server Virtualization


And of course, there’s been a lot of work so far…Pushing towards fully open software control layer, commoditized hardware

NFV for Virtualizing Devices


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

Recreates the Silo Inefficiencies of the Legacy Era


“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

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
