1. What is the Big Picture relevance of LSO Sonata APIs for the industry?

The communications industry is in the midst of a multi-year transformation to dynamic and assured services across a global ecosystem of automated networks, as envisioned in the MEF 3.0 framework. With each day, consensus builds that service providers must become more cloud-like and automated to deliver more powerful networking solutions with unprecedented user- and application-directed control over network resources and service capabilities.

It will not be enough for providers to offer dynamic connectivity and virtualized services over just their own networks. Providers must transition from operating as independent islands of excellence to being integral players in a worldwide business federation of cloud-like networks that support standardized dynamic services across multiple operators. This opinion of MEF is based on direct engagement with top decision-makers and influencers employed by the biggest service providers in the world, along with many of their wholesale buy and sell partners.

To realize this vision, MEF has advanced initiatives related to a full family of standardized MEF 3.0 services – including Carrier Ethernet, SD-WAN, Optical Transport, and IP – as well as standardized MEF 3.0 LSO (Lifecycle Service Orchestration) Sonata APIs that are foundational to orchestrating these services across federated networks.

LSO Sonata – Part of the Digital Transformation Journey
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 full suite of planned LSO Sonata APIs deals with serviceability (address validation, site queries, and product offering qualification), product inventory, quoting, ordering, trouble ticketing, contracts, and billing. Implementation of LSO Sonata APIs will drive frictionless inter-provider business processes and faster service delivery across the service provider community.
