Appendix - Transport SDN use cases from several perspectives

 

Sellable use cases (direct business impact):

  • Transport network as a service for internal or external customers (e.g. OTT providers)
  • Bandwidth on demand (BWoD), bandwidth calendar
  • Private optical networks; optical virtual private networks (O-VPNs)
  • Service / path optimization on the basis of application requirements
  • Topology as a service

Supporting use cases and functionality (indirect business impact):

  • Automated service provisioning and decommissioning: initial, change, migration
  • Proactive service assurance
  • (Close to) real time network state awareness (including inventory, utilization, quality, etc.)
  • IP-Optical integration
  • Intelligent automated network optimization, including real-time
  • Unified and transparent multi-vendor-capable APIs and protocols between sub-systems and to external systems

Building blocks:

  • Network resource and service discovery and visualization capabilities
  • Information about the network (logs, events, inventory, etc.) is stored and available for “big data ready” applications
  • Coordinated “big data capable” analytics
  • Coordinated multi-layer path computation
  • Coordinated maintenance, maintenance window
  • Path diversity (link, node, shared risk link groups)
  • Intent-based networking
