3 T-MANO In lined with SK Telecom s unified orchestration strategy, T-MANO provides control and management of the entire life-cycle of network infrastructure resources, functions, end-to-end network 4 1 Standardized NFV MANO Framework Local NFV Orchestrator Generic VNFM Common VIM End-to-end Network Orchestration Multi-domain(RAN, Transport, Core Network) network slice design & LCM Support multi-vendor VNF with open API Service Orchestration Management of dynamic network segment optimized for requirements & policies Service chaining (SFC, FMSS) Policy server, BSS interworking Standard Data model T-MANO Multi-vendor, operator Interoperability Orchestration, configuration automation

4 T-MANO in Action: Dynamic End-to-End Network Slicing Order LCM Service LCM BSS (Order Life-cycle mgmt., Sales, Marketing, CEM, Billing) Service LCM E2E Network Slice LCM Network Resource LCM Day-0 Configuration (Deployment) Config.
