› Conclusions

AGENDA


CHALLENGE & SOLUTION

› Service Personalization leads to increased

Cost and Complexity

› Where is the sweet spot of being a Smart

operator

› Non SDN “service chaining” is often

Inefficient, or Subscriber-unaware & Static

THE CHALLENGE

› Service Chaining allows Real Time, Dynamic, Low

Complexity and Scalable Service Personalization

› The Results

- Service Deployment in Minutes

- Operational Simplicity

- Carrying live traffic today S

› Conclusions

AGENDA


IT INFRASTRUCTURE VIRTUALIZATION BARRIERS & OPPORTUNITIES

SMEs › Owning an IT infrastructure is just expensive

(e.g., high number of small branches)

› For fast growing startups, requirements change

and scaling is hard with “box solutions”

› “Try and Buy” is compelling but can be too

complicated

› Don’t have the time and resources to setup and

maintain IT infrastructure

Operators › Revenue growth opportunity from

- Cloud as a Service

- Networking-aaS

- Infrastructure-aaS

- Software-aaS

- BYOD

› However limited ability to service enterprise

customers

- Logistics & scalability of current model of

service

- Significant delay to deploying new services

- Competing against OTT cloud providers

offering “similar” services


VIRTUAL ENTERPRISE SOLUTION BENEFITS

› Operator reduces cost for CPE

› Enterprise outsources IP, Communication Services and

Enterprise Applications to best-in-class provider

› Builds on Ericsson competence in Cloud, NFV and SDN

› Operator moves up in the value chain + Lock-in effect

› Enterprise Considerations

- Maintain multiple isolated network slices

- Enforcing & Monitoring SLAs and KPIs

- Opening up networking services to the

enterprise

- Providing a service catalogue to

enterprises

- Requires a robust cloud platform to

support, storage, voice and data services


Business Layer › Expose Services, SLA, KPIs to enterprise

› Triggers orchestration and network change

› A framework for efficient work flow for innovation

Resource Layer › Compute Resources
