MEF’s open-standard LSO Operational APIs are implemented at one or more of three interface reference points in the LSO Framework—LSO Allegro, LSO Interlude, and LSO Legato.
Inter-provider APIs for automating operational functions east-west between companies’ respective business support systems (BSSs).
LSO Operational APIs enable sellers of services to share key elements of the lifecycle of a service with their buyer customers, once it has been ordered and provisioned, all the way through to its decommissioning.
The LSO APIs at LSO Allegro allow enterprise, application and developer customers to automate their operational interactions with their service provider partners for activities such as service change, performance monitoring and fault management.
The LSO APIs at LSO Interlude coordinate a portion of digital LSO services within the partner domain that are managed by a service provider’s Service Orchestration Functionality (SOF), within the bounds and policies defined for the service.
Through LSO Interlude, the SOF may request initiation of technical operations or dynamic control behavior associated with a service with a partner network domain. Such requests must be within the constraints set forth in the policies associated with established services and performed without impacting business applications.
Intra-provider APIs for automating operational functions north-south within the service provider, between its business support systems (BSS) and its operating support systems (OSS).
LSO Operational APIs also enable service providers to automate key elements of the lifecycle of a service internally, once it has been ordered and provisioned, all the way through to its decommissioning.
