Carriers on-net SDN/NFV deployment is not enough

• Commercial discussion

• Inter-connect discussion

• API interface discussion

Service Alliance

Using standard based APIs, build service alliances with carriers who have similar vision on end-to-end Self Service orchestration across multiple carrier networks

24

Self-Service Orchestration Alliance (showcase)MEF 3.0 – Service Fulfillment and Activation across multi-operator networks

• Create a L3VPN service spanning at least 3 Operators, terminating on a VM in a cloud service and integrate SD-WAN

• Use the L3VPN service for cloud services (e.g. stream video to a user device)

• Use LSO Innovation Platform to develop SOF functionalities and applications

• The setup is being turned into permanent MEF sandbox project, open to all MEF members.

Conclusions

Market Drivers

• New digital business models are emerging due to convergence of Cloud, Social, Mobility, Information, & IoT. Requiring elastic network services.

• CSP’s require transformational changes with SDN, NFV & LSO - to improve Network Control, Agility & Operational efficiency.

Roadmap

• SDN, NFV, LSO enable - On-line Quote & Order , Self service orchestration, BW on Demand, vCPE, Service Chaining

• PCCW Global is showcasing some of these services at MEF17 PoC.

Challenges

• Inter domain, Inter Carrier integration challenges remain to be overcome

• Standards driven Eastbound APIs are a must to enable LSO in an inter-carrier environment.
