  Transport Network Virtualization Networkresources dynamically allocated for high utilization Resources can be partitioned into slices for service or user Control exposed through open interfaces → Proprietary, vendor-specific silos → Complex to operate, integrate across vendors/technologies → Logically centralized, vendor-agnostic control and service orchestration → Virtualization of physical network resources OSS Platform Proprietary OS Vendor X HW Proprietary OS Vendor Y HW Proprietary OS Vendor Z HW Current Networks Software-Defined Networks OSS Platform/SDN Apps Virtualized Multi-vendor Multi- domain Network SDN SW SDN-enabled HW Open APIs Vendor EMS SDN Control Infrastructure
