  • Major concern so far has been to provide network capacity and wireless access
  • Figure 4. Open-loop video delivery
  • Figure 9. Cognitive networks can learn how to differentiate ‘good’ from ‘bad’ signals, recognize viruses, and adjust to extreme perturbations.
  • Future Internet: how diverse disciplines will help redesigning our networks

    1. 1. Future Internet:How diverse disciplines will helpredesigning our networks Prof. Antonio LiottaEindhoven University of Technology, NLhttp://bit.ly/autonomic_networksTwitter: a_liotta
    2. 2. What does it take to be a ‘generative’ Internet?• Apps: ~0.5 million, 600 new apps/day• Multicast IPTV: $38m expected revenues for 2013• Internet video: 0.8 Zettabytes (1021bytes) in 2014• Connected ‘things’: 1 trillion in 2020• Network so complex that’s Internet Map coloured by IP addresses hard to draw on a map (Courtesy of W.R. Cheswick)Prof. A. Liotta 2
    3. 3. Future Internet: what are we up against?Explosive combination of sheer scale and diversity of things Building ICT autom. Security Energy & Safety Consu- mer & Retail Home Health- Transpor care Indust. tation Autom.(*) Source: Cisco dataforecast, Feb 2011 Prof. A. Liotta 3
    4. 4. What are we up against? Insurmountable barriers Each ~100 mWatt transmission power Each 1 Gigawatt supplyProf. A. Liotta 4
    5. 5. Sheer complexity (as in “complexity theory”)• Properties of whole can’t be inferred from properties of individual parts• Individual components interact nonlinearly, leading to emergent behavior• Constantly evolves and unfolds over timeProf. A. Liotta 5
    6. 6. Natural networks work thanks to adaptivity and learning Eminent examples: • Human brain • Immune system • Ecosystems • Insect colonies • Most social structures • … Brain synapses (Source: www.chiefscientist.gov.au) Prof. A. Liotta 6
    7. 7. Today: a complex system operated simplisticallyOver-dimensioned Over-dimensioned No idea whether servers data flows user is satisfied Over-provisioned Over-specified networks terminals 7
    8. 8. Good news! A billion dollars available to re-think the Internet “The growth of the Internet is strictly intertwined with socio-economic, environmental and cultural developments” EU FIRE programProf. A. Liotta 8
    9. 9. Unique opportunity to integrate knowledge already available outside of the networking community Phycology Law Social science Physics Cybernetics Natural Systems sciences ecology Computer Graph science theoryComputational intelligence learn & evolve FI taming complexity Complexity theory Cognitive Prof. A. Liotta Networks 9

    11. 11. Networks too can learn how to deal with new perturbations. Example video delivery conditions News clip Sport clipOriginal Clips 50 50 100 100 150 150Difference in 200 200 Temporal 250 250 300 300 Motion 350 350 400 400 450 450 500 500 550 550 100 200 300 400 500 600 700 100 200 300 400 500 600 700 Initially we train the Reinforcement Learning network to handle teaches how to handle Prof. A. Liotta “News over Laptop” “Sport over Phone” 11
    12. 12. Networks too can learn how to deal with new perturbations. Example video delivery conditions ‘Sport over mobile phone’ QoS probe actuators Optimizing QoE Machine QoE measure QoS prediction Learning or inferenceProf. A. Liotta 12
    13. 13. Can we use computational intelligence to build ‘nature-like’ computer networks? Multi-disciplinarity SOLUTIONS Hidden patterns Emergent behavior Self-regulation Learning 13
