   - Flexibility and agility
   - Integration from “in hardware”
   to “in software”
   - Innovations and upgrades
   from “per all-in-one nodes”
   to “per each component”
   - Target Domain
   - metropolitan
   - DC/Cloud Interconnect

   - 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
