LSO Presto

Intra-domain network orchestration and automation.


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.

LSO Presto Interface Reference Point

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.

LSO Presto API Advantages

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.

Vendor-specific APIs vs Standard 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.

What Can I Achieve with MEF LSO Presto APIs?

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.

MEF LSO Presto API advantages:

  • Reduced API development cost for service providers.
  • Lower implementation costs for service providers.
  • Faster service provisioning.
  • Accelerated time to revenue.
  • Enhanced market accessibility for technology providers.
