    - Flexibility and agility
    - Integration from “in hardware”
    to “in software”
    - Innovations and upgrades
    from “per all-in-one nodes”
    to “per each component”

    - The journey to Software Integration of multi-vendor dis-aggregated
    devices is long and difficult
    - Lots of features to be realized among multi-vendor devices
    - Discovery, path computation, power control, protection, monitoring, etc..
    - Common Open API is needed
    - TAPI is the most possible candidate, but there are some missing parts
    from the software integration perspective
    - ODTN is collaborating with OTCC/TAPI and growing into each other
    - Multi-device transaction and config state management features are needed
    - But there are no candidates in current Open SDN controllers
    - Now considering to implement these features in ONOS
