and outer partner (e.g. MVNO, big

enterprise) have specific requirements

• Cloud based service mode can

provide the best solution: resource

sharing, rapid supply, self service

• Uniform management system

provides integration of service

programmability, domain

orchestration and DevOps

functionality

• Via API & SDK to facilitate the creation of

ecosystems which benefit different planes

• IaaS: NFVI resource as a Service for partners

• PaaS: VNF, common component, operating

environment and SDK as a service for partner

• NaaS: network service for customer/partner

Service Automation via Nested & Multi-Domain Orchestration

• Nested and Multi-Domain RO

multi-vendor

multi-technology

multi-administration

• Slice orchestrator supports E2E function

orchestration of PNF, VNF & transport

• Inter-slice orchestration considers

common NFs among multi-slices

• Transforms SLA to KPI, network

services & slices requirements

• Integrated/Separated Service

Assurance to implement policy based on

data analytics, e.g. modifying a slice or

creating a new slice
