About MEF 55 (What is LSO?) LSO provides for the orchestrated management and control of Third Network Connectivity Services across all internal and external network domains from one or more network operators LSO Reference Architecture characterizes the management and control domains and entities that enable the cooperative LSO capabilities LSO overcomes existing complexity by defining product, service, and resource abstractions that hide the complexity of underlying technologies and network layers from the applications and users of the services Within each provider domain, the infrastructure may be implemented with WAN technologies, as well as NFV and/or SDN Not only dramatically decreases the time to establish and modify the characteristics of the Connectivity Service, but also assure the overall service quality and security for these services

LSO RA Phase 2 Operational Threads

Describe Target Use Cases & Interactions (Example) Serviceability and Ordering

Next Steps Describe each of the MEF LSO Interface Reference Points (IRPs) within the ONAP context. For each IRP provide the functional description of target ONAP capabilities for interactions Describe deployment scenarios Use ONAP Use Cases as the basis for identifying key external interactions & apply MEF LSO Operational Threads
