• Loose coupling between the overlay and underlay

Scalability •

Controller federation

• Multi-domain

Fat vs. fit VNFs

Thick/fat VNFs Virtual implementations of physical functions

–Complex multiservice configurations – Integrated load balancing, high

availability, AAA IF –Scale in and out internal to VNF

Drawbacks –Complex to implement, integrate, and

test –Elasticity is difficult to implement –Slow rollouts, long time to revenue

Thin/fit VNFs (apps)

Single-service atomic network functions

– In-network load balancing, high availability –Single interface to AAA –Scaling by adding network function

instances

Advantages –Simple integration and testing –Elasticity by simple integration with

orchestration –Fast rollouts, short time to revenue

Challenges – All functions sized for peak – Slow new service deployment – Separate load balancers

needed per function

Virtualized With SDN

Virtualized, but no SDN

Advantages – No need to send all traffic

through all devices – no overprovisioning

– Agility – add new services without affecting other services

The need to be able to launch and try new services with minimal risks

The need to offer highly personalized services SDN enables policy integration

to create scalable per user/per application traffic flows

NFV implementation enables matching capacity expansion to revenue growthThe need to optimize Gi

LAN capacity utilizationSDN enables easy plug and play of new service functions into the Gi LAN and service path

Traffic growth pattern putting pressure on the gateway

– Increasing active/idle signaling load – Increasing peak throughput load

Traffic composition changing – Video upload & download increasing – Emerging applications need lower latency and/or

local only connectivity – “Private LTE” networks, IoT apps
