Automating IntraProvider Operations with LSO APIs LSO Presto

Automating Intra-Provider Operations with LSO APIs: LSO Presto Roadmaps & Use Cases Bartosz Michalik, Principal Architect, Amartus MEF Q 3/19 Members Meeting, July 2019

LSO Presto API delivers benefits to both service providers and technology suppliers. Reduced product costs • standard APIs prevent each vendor from having to implement every providers’ APIs Reduced implementation costs • Service providers don’t have to implement a vendor’s proprietary APIs. Reduced development costs • Common models ease internal development of microservices by eliminating mapping between proprietary vendor models for internal logic.

LSO Presto APIs are based on FCAPS and Common Model Once the LSO interface is selected, the functionality of the API is selected. The typical API functions are: • Configuration/Activation • Fault/Events • Telemetry/TCAs • Accounting/Authorization • Security ONF TAPI provides an excellent common model that can be leveraged at all LSO interfaces for all FCAPS.

Network Resource Modeling (NRM)

Integrating with ONF TAPI • • SP Domain Modeling and corresponding API development should be based on common models. MEF NRP is based on ONF TAPI. Business Applications LEGATO (BUS: SOF) Service Orchestration Functionality PRESTO (SOF: ICM) Infrastructure and Control Management (ICM) (examples are SDN Controllers and NFV MANOs) TAPI provides a set of reusable network software patterns that can be applied at any layer within the LSO stack. These patterns include: Connectivity, Topology, OAM, Path Computation, Virtual Network and Notification Services. These patterns are the cornerstone for supporting of all FCAPS+T/I (Fault, Configuration, Accounting, Performance, Security, Topology and Inventory).
