MEF’s Third Network Vision Enable agile networks Deliver assured connectivity services Orchestrated across network domains Between physical or virtual service endpoints 4 www. mef. net

Lifecycle Service Orchestration www. mef. net

Lifecycle Service Orchestration capabilities Backbone of the Lifecycle Services provided by The Third Network Provides orchestrated management and control of Connectivity Services 6 www. mef. net

Lifecycle Service Orchestration (cont) Defines product, service, and resource abstractions Abstracts complexity from applications and users of Connectivity Services Infrastructure-agnostic (WAN technologies, NFV, SDN) 7 www. mef. net

Models in Context www. mef. net

LSO Engineering Methodology Enables the transformation of LSO capabilities into interoperable, specific, consistent, and verifiable designs and implementations Generates re-usable engineering specifications and artifacts Captures LSO requirements, capabilities, functionality, behavior, processes, information, interfaces and APIs 9 www. mef. net
