Operation Cloudification via Multi-Tenant, Multi-Service, XaaS
• Both inner partner (e.g. sub-company)
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
