Key Ideas

• data (configuration, routing, measurement) | models (topology, demands, routing) | analysis

  • Generate accurate global views of the network, and provide mechanisms to infer network-wide implications of changes in traffic, configuration and control
  • Architecture—separate systems for measurement, models, methods to populate models, analysis
    • Can and must evolve with change to underlying infrastructure and network architecture
  • Interfaces for modules above
    • E.g., design and optimization (e.g., Bernard Fortz and Mikkel Thorup, "Internet Traffic Engineering by Optimizing OSPF Weights," Proc. IEEE INFOCOM, March 2000. http://www.ieee-infocom.org/2000/papers/165.ps)

• … | (informed) provisioning and reconfiguration

  • Closing the loop…
  • Improving performance and making more efficient use of network resources
