Increasing agility throughout whole service lifecycles



ONAP (Open Network Automation Platform)

Growing ecosystem and solution maturing

▪ The first release “Amsterdam” has been

available since November 2017

▪ The next release “Beijing” will be available in

May 2018


▪ ONAP supported by major Operators, Vendors, Integrators

▪ Growing community and contributions

▪ Broad recognition – « 2018 Open Source Rookies of the Year » (honoree from Black Duck Software)

Participation of companies in Open Source

initiatives has its market and economic

reasons.

Significant reduction of time to market. The

DevOps approach becomes more efficient with

CI/CD – quicker and less „painful” introduction of

changes. Takes advantage of automation and

micro-services. Containers allow to take

advantage of the full potential of DevOps.

Development model target

Virtualization layers requires a resource

contracting model – New Resource

Contracting set between VNF NFVI

consumer and NFVI Provider :

engineering, capacity planning, technical

support and Partner management

challenges, formalize resource billing

Virtualization will introduce a new Life

Cycle Management – The border between

Engineering /Integration functions and

Operations blurs.

VNF release management will become

more agile (DevOps approach) thanks to

the separation of the Network Functions

and Infrastructures


Updating the way services are designed and created

How does it drive business opportunities?

▪ Establishment of on-demand secure

links

▪ Zero Touch Provisioning

▪ Support for cloud services

Solution Business OutcomesProblem statement

▪ Improved application performance

▪ More precise business data

▪ Reduced management complexity

▪ Improved manageability and incident

resolution time due to end-to-end

visibility

▪ Digital transformation

▪ Poor quality, Internet only,

access

▪ ISP doesn’t support SLA,

▪ limited IT staff and knowledge

▪ Low security of DIY VPNs

▪ Cloud service problems

Key Takeaways



Key takeaways

1. Demand for new services will drive network function virtualization and 5G

deployment prompting operating model changes for telcos, not the opposite

2. New service architectures will emerge – ways in how services will be sold,

delivered and supported will fundamentally change

3. Traditional services and legacy infrastructure will coexist making the transition

more complex and difficult

4. Faster maturation & better interoperability thanks to the choice for open source

solutions such as ONAP orchestrator as a critical component

5. Contractual responsibility and liability of VNF providers versus infrastructure

providers (as for performance failure or outage) to be revisited, e.g. positioning of

the integrators
