As part of the LSO Reference Architecture, LSO Presto APIs enable service providers to orchestrate both SDN/NFV technologies and legacy infrastructure, interfacing with SDN controllers and NFV orchestrators, as well as legacy infrastructure control management (e.g. element management systems).
LSO Presto APIs are already defined for Carrier Ethernet and Optical Transport subscriber service resource management, covering functions specific to each, such as resource configuration, provisioning, path computation, and performance monitoring.
See MEF’s Technical Standards & Educational Materials for LSO Presto
LSO Presto is the Interface Reference Point between the service orchestration functionality and infrastructure control and management (e.g. a domain controller) within a service provider’s domain.
By using a standard set of APIs for communication between service orchestration functions and the domain controllers within a provider domain, the provider is able to deliver enhanced service agility and dynamic functions, while realizing operational efficiencies.
Technology providers who supply either service orchestrators or domain controllers are able to focus product development on value-added functionality as opposed to ensuring integration with multiple proprietary products within the ecosystem. This ability reduces development costs, as well as accelerating the evolution of high-value functions that providers can leverage to ultimately enhance the enterprise customer experience.
Given the significant number of in-house solutions developed within providers, having a common standard proves more valuable as the number of potential integrations spans both commercial product integration as well as each provider’s in-house integration needs. The resulting gains for service providers have led to significant work within MEF on the LSO Presto APIs.
Common, industry-standard APIs remove the costs born by multiple proprietary vendor APIs, incurred by both service providers and the technology providers themselves.

MEF 120 Lean NFV Overview and Framework — 2022 May
Product Portfolio: LSO Presto, LSO Adagio
Lean NFV represents an approach to implementing Network Functions Virtualization in the context of MEF LSO.
I want to investigate further. See all LSO Presto resources:
First and foremost, MEF LSO Presto APIs enable the dynamic management required to deliver the necessary agility that enterprise customers require from their digital services. Furthermore, standard APIs allow providers to avoid the cost of having to implement technology suppliers’ proprietary APIs. Savings in implementation time, costs, and testing lead to faster service provisioning, time to market, and time to revenue.
Technology providers or vendors are able to lower their product management costs, focus on product innovation, and enable a gateway into the market for any service provider’s service orchestration functionality, be it commercial or in-house developed.
