MEF is pleased to announce two major developments related to MEF 3.0 LSO Sonata APIs. MEF launched the pilot MEF 3.0 LSO Sonata certification program for inter-provider service automation, with an initial focus on automating ordering of MEF 3.0 Carrier Ethernet Access E-Line services. Simultaneously, MEF introduced LSO Sonata SDK (Software Development Kit) Release 3 with APIs for inter-provider serviceability, product inventory, quoting, and ordering. Together, these important steps will accelerate implementation of standardized LSO Sonata APIs worldwide, driving frictionless inter-provider business processes and faster service delivery across the service provider community. 

“Certified MEF 3.0 LSO Sonata APIs will be the critical enabler for orchestrating MEF 3.0 services – starting with Carrier Ethernet and extending to SD-WAN, Optical Transport, and IP – across a global federation of automated networks,” said Pascal Menezes, CTO, MEF. “More than 50 service providers around the world have voiced support for development and adoption of LSO Sonata APIs to realize time-to-revenue and profit goals. We expect a core group will participate in the pilot certification program, leading the industry shift from manual inter-provider processes to dynamic service automation.”

LSO Sonata Standardization

LSO Sonata API standardization is part of a comprehensive MEF 3.0 effort to standardize multiple sets of LSO APIs enabling service automation across providers and over multiple network technology domains. LSO Sonata APIs relate to the interface reference point within the LSO Reference Architecture that supports business-to-business interactions between service providers. LSO Sonata APIs combine service-agnostic TM Forum Open APIs with MEF 3.0 service definitions. The collaboration effectively secures a service provider’s investment in both MEF and TM Forum while delivering an accelerated time-to-market and time-to-revenue. The full suite of planned LSO Sonata APIs deals with serviceability, product inventory, quoting, ordering, trouble ticketing, contracts, and billing.

MEF 3.0 LSO Sonata Certification

MEF 3.0 LSO Sonata certification enables buyers and sellers of wholesale MEF 3.0 services to validate that the full suite of their APIs used for inter-provider business transactions comply with MEF standards. The certification program will help companies develop, test, and certify all LSO Sonata APIs as they are released. This new certification builds upon the widely recognized MEF certification program that has delivered hundreds of certifications to Carrier Ethernet service and technology providers and fueled creation of today’s $80+ billion global CE market. 

MEF 3.0 LSO Sonata Certification Pilot

The MEF 3.0 LSO Sonata certification program – conducted in concert with MEF testing partner Iometrix – starts with a pilot to generate industry momentum worldwide. The pilot involves three major steps associated with published MEF 3.0 CE and LSO Sonata standards:

1.       Certify MEF 3.0 CE Access E-Line Service. Service providers validate compliance with MEF 3.0 CE Access E-Line service standards as described in the MEF 3.0 CE Certification Blueprint.

2.    Develop MEF 3.0 LSO Sonata Ordering API. The API test platform helps companies optimize development of the LSO Sonata Ordering API based on Ethernet Ordering Technical Standard: Business Requirements and Use Cases (MEF 57.1) and LSO Sonata SDK Release 3. The platform provides a structure within which API developers can develop code covering various use cases in an optimal manner and pre-validate their code at every step of development.

3.    Certify MEF 3.0 LSO Sonata Ordering API. The final stage of certification validates conformity of the LSO Sonata Ordering API to the MEF LSO Sonata Certification Test Requirements (MEF 92) working draft on the MEF wiki, which together with the MEF 3.0 CE Access E-Line service certification provides a fully compliant orchestrated service ready to interact with partners across the globe.

LSO Sonata SDK Release 3

LSO Sonata SDK Release 3 includes a set of deliverables that enable market adoption of LSO Sonata APIs for serviceability (address validation, site queries, and product offering qualification), product inventory, quoting, and ordering. The SDK includes published and draft standards listed below covering business requirements, use cases, and attributes that serve as the basis for the associated APIs and data models. Available on the MEF public GitHub, the SDK also includes Swagger data models, product payload specifications composed of MEF 3.0 services, and other artifacts that enable a developer to rapidly build out these Sonata LSO APIs within their business systems.

While initial LSO Sonata API work relates to orchestration of MEF 3.0 Carrier Ethernet services, further advancements will support the full range of MEF 3.0 services – also including Optical Transport, IP, SD-WAN, Security-as-a-Service, etc. – without changing the basic API structure itself thanks to the polymorphic approach used in collaboration with TM Forum.

LSO Sonata at MEF19

LSO Sonata and other LSO APIs will be integral to many MEF 3.0 Proof of Concept Showcase demonstrations and conference sessions at MEF19, held 18-22 November 2019 at the JW Marriott LA LIVE in Los Angeles, California. Visit http://www.MEF19.com for registration and event information.
