  1. Acreo – Future work Pontus Sköldström

  2. Where are things moving? Interesting SDN applications SDN Improved controller design Cross-layer optimization Support more technologies

  3. SDN applications Interesting SDN applications SDN

  4. SDN applications – BGP freecore • Complicated to configure • Complicated to manage • Expensive devices

  5. SDN applications – BGP freecore • Apply SDN! • Similar to demo, but BGP • Single BGP node • Cheap devices • RouteFlow project • http://cpqd.github.com/RouteFlow

  6. SDN applications – BGP freecore • Lots and lots of entries  • Can we reduce the memory requirements?

  7. SDN applications – BGP freecore • Normally, full forwarding tables everywhere • What if we split the forwarding table and distribute it?

  8. SDN applications – BGP freecore • Cleverly split the forwarding table into multiple pieces • Install to switches, add tunnel magic • Dramatic reduction in memory • Slight increase in delay

  9. Wherearethingsmoving? SDN Improved controller design

  10. Improvedcontrollers - Abstraction • Earlier we mentioned abstractions, but how? • Abstract a whole network to a single node • Scalability, simplicity • Combine nodes into one • Grow single nodes, “super-nodes”

  11. Improvedcontrollers - Abstraction • Need something similar as in the BGP free core example • But how can we do it for full OpenFlow rules?

  12. Wherearethingsmoving? SDN Support more technologies

  13. Support moretechnologies - Opto • Basic support for Optical nodes more or less done • Simple wavelength setup • Not a big gain compared to existing systems

  14. What if we add support for basic monitoring (e.g. BER) • Much simpler with the SDN approach • Detect degradation, reconfigure network

  15. Add support for modifying physical parameters (like modulation) • Tune network based on monitoring input • Again, the SDN approach makes it easier

  16. More physical parameters! • Tune modulation format, spectral width, based on current demand

  17. Wherearethingsmoving? SDN Cross-layer optimization

  18. Cross-layeroptimization • Highly reconfigurable link technologies (both optoand radio) • More dynamic routing schemes • How can we combine these to optimize for: • Latency, throughput, energy efficiency?

  19. The end! • Any of this sounds interesting? • We’re looking for partners, e.g. FP7 call 11 in Spring 2013 • Any questions? • Pontus.skoldstrom@acreo.se, Anders.gavler@acreo.se • Wolfgang.john@ericsson.com • Elisa.bellagamba@ericsson.com • Thanks for listening!
