    Open APIs
    Only Open APIs with public models will be used.
    Reach industry consensus and agreement on Open and Public APIs
    Open and Standard API:
    - provide layers of abstractions
    - enable plug and play
    - mandate interaction between software and hardware
    - mix and match of components
    - multi-vendor integration

    - Well know API
    - Supported already by many vendors
    - Proper abstraction model for transponder devices capabilities and information
    - Defines capabilities at correct level for programmability but also abstraction
    from physical details
    - Capability and Flexibility to support vendor specific features
    - Can represent both multi-layer w/ and w/o OTN
    - Extensible and Open Source
    - Well know API
    - Extensible and Open Source
    - Tested and deployed (See Interop Testing)
    - Proper abstraction for high level optical domain programming
    - Can represent both multi-layer end to end provisioning with optical
    parameters
    - Great community of vendors and Service Providers
    Service Provisioning
    1. OSS/BSS requests connectivity-service with TAPI
    2. Connectivity services and provisioning config is stored in
    distributed Maps for redundancy and failover
    3. ONOS translates into Optical Intent and TX configuration
    4. provisions a connectivity service through TAPI on OLS
    5. Logical channel (cross-connection from client to line side) and
    wavelength Tuning through Openconfig on Transponders
