Lesson learned from commercial deployment
● Customer’s voice to SDN/NFV network transformation➢ SDN/NFV advantages are strongly relevant to network orchestration capability
▌Customer’s requirement to SDN/NFV ● TCO(CAPEX/OPEX) reduction
● Visualization of operational effectiveness and quantitative value ● better ROI ● legacy migration with virtualization platform ● new service creation and new business opportunities ● rapid service creation and service agility ● reduce number of employee with operational knowledge, skillset and experience ● Introduce new business model
▌SDN/NFV benefits are completed by End-to-end Service Orchestration

• Customer Order Entry • Manage existing customer orders (modify, pause, terminate, restart, etc.)
• Order calendaring (duration, periodic/scheduled intervals, etc.)
• Reporting and Visualization • Online monitoring of SLA parameters and KPI data • Per flow/tenant level reporting capability • Order status monitoring • Service usage • Service path viewing
• Customer Support • Trouble ticketing • Account view • Billing queries

Multi-vendor/Multi-domain PoC Summary
• The next challenges: (partially demonstrated at MWC2016) 1. Multi layer network optimization 2. Cloud service and policy aware network provisioning, NFV
collaboration 3. Higher availability for geographically distributed controller 4. Monitoring and Analytics for network resource optimization ** Please come to NEC booth. You can see the Demo Video at MWC2016
PoC Results a. Customer order entry/order calendaring (duration, periodic/
scheduled intervals, etc)/order status monitoring/billing has been demonstrated
b. New multi-domain optical service creation have been less than 2 min
c. Multi-domain service restoration have been less than 1.5 min d. Service path viewing
