The Third Network: LSO, SDN and NFV
2
Market Trends
• Subscribers want more control over their network service – On Demand, Self Service, Elastic, Pay as you Go, Ubiquitous
• Services not bounded to physical interface, single provider – Could begin on a mobile device and end on a VM
– Could begin at one provider and end at a data center
• NFV & SDN are changing how networks are being built – Physical Network Functions Virtual Network Functions
– Layered approach to separate control plane from data plane, software from hardware

We have Great Expectations!
I can discover new apps that are instantly available
… delivered with blinding speed over all networks, anywhere
When I need performance, I’ll pay a premium.
Perfect QoS … always on – no excuses
In the future …

Today’s Two Modern Data Networks
On-Demand & Ubiquitous Performance & Security
Internet
Lack of Agility No Service Assurance
Imagine a new type of network service combining the best of both worlds and removing the limitations …

A New Type of Network Service
• Agile – Delivery of new, dynamic, on-demand services
• Assured – Delivery of performance and security guarantees
• Orchestrated – Delivery of automated service across service providers
What could be the impact on our everyday lives?

We have some great building blocks
… but separately and collectively they still don’t meet our stated expectations
Do we have anything else?
NFV SDN + +
So, that’s 20 megs for 6 months starting in June, Right?
No, my app needs 100 megs now for
the next 2 hours!!!!
We have an OSS/BSS chasm No standards for automation
Making it a Reality - The Challenge: “Why is it so hard to deliver it Today?”

What’s needed to deliver the Third Network?

Three Major Industry Initiatives
MEF is now standardizing Lifecycle Service Orchestration • With layered abstraction to automate Network as a Service per
layer, starting at Carrier Ethernet layer or domain
Collaborating SDOs
NFV and SDN • Concerned with infrastructure functions & control • Not concerned with network connectivity services businesses
or individuals actually purchase
Lifecycle Service Orchestration
Lifecycle Service Orchestration • This is where the MEF completes the picture …

Initial work under way • Defining Lifecycle Service Orchestration functions
• Fulfillment, Performance, Control, Assurance, Usage, Analytics, Security, Policy
• Extending the Information Model: dynamic & protocol independent • Developing Service Orchestration APIs for portals or business
applications as well as for SDN, NFV, existing WAN, where needed
