  2. Once upon a time, …, in the beginning

  3. And now !

  4. Happy birthday !!!! • Three anniversaries in 2009 • 20 years of WWW • 30 years of USENET • 40 years of Internet

  5. Internet: a global media

  6. The “Hourglass” as the model

  7. From clear layers to spaghetti … ICA/Citrix KaZaa SOAP XMLRPC L2TP DNS IRC HTTP SMTP ICMP UDP TCP ICMPv6 IPv4 IPv6 PPP 802.1q PPPoE Ethernet

  8. The Real Internet looks like

  9. Solutions proposed Solutions in use Understanding of problem area NewCycle Industrytransfer The R&D « Learning » Curve Solution complexity time early middle late 9

  10. Applications Regulation Economy Management Complexity Opposite forces Are We’re here or there or both! New challenges in Networking Solution complexity time early middle late 10

  11. Nowadays … Pocket switched networks Thank you but you are in the opposite direction! I can also carry for you! I have 100M bytes of data, who can carry for me? Give it to me, I have 1G bytes phone flash. Don’t give to me! I am running out of storage. Reach an access point. There is one in my pocket… Internet Search La Bonheme.mp3 for me Finally, it arrive… Search La Bonheme.mp3 for me Search La Bonheme.mp3 for me

  12. Go back to basics • A network is build of components • Local in a node or distributed • Sitting in one layer or crossing layers • Tightly or lightly coupled • Cooperating to transmit information from point to point. • Actual layered architecture is just one specific type of collaboration • Collaborating through protocols • Autonomous networking idea • Moving from pile view to puzzle view • Need for new theoretical framework

  13. Cooperation ? • Full Cooperation • Do the best possible behavior to reach a goal • Assuming full collaboration • Is the goal achievable ? • How to achieve the goal ? • Multi-user information Theory • Non–cooperative • Selfish behavior • Different rational goal • How to mitigate conflicting rational goal ? • Game theory • Malicious behavior • Harmful goal • How to contain irrational objectives ? • Behavioral inference

  14. Cooperation framework • Each Node implement a forwarding function • The forwarding function implement the cooperation

  15. Flooding Routing Distributed computation Network coding Any other ? Forwarding function Examples

  16. Who cares? CLEAN SLATE VS EVOLUTIONARY?

  17. Exploring the future Internet • What is broken and need to be fixed? • What is the right approach? • Is the clean slate approach appropriate? • Any transition methodology? • How difficult do you expect that a new architecture would be adopted? • We have a few examples on how difficult it is to change the current architecture: multicast, mobile IP, Intserv/Diffserv, and IPv6. • Any enabling factor?

  18. Explore the possible Future(s) of the Internet • Realistic view • Continuous evolution and change • Usage and Services will become predominant • User-centric approach to system design • On-line social networks • Greening the Internet • Other factors than technology will be instrumental • Economics, Social behaviors, Entry cost, Regulation

  19. A single architecture ? • The future Internet might be Polymorphic • Various research projects, scientists and “people” will propose new ideas • GENI, FIND, FIRE, etc… • Building blocks • Architectures • Flexibility is the major constraint of future Internet

  20. Flexibility or the internet contortionist • to accommodate Future Internet polymorphism • Enable different cooperation paradigms in parallel. • Enable easy deployment of new application deployment. • Without raising routing and addressing to the application • As Peer to Peer and overlay networks • A network where one could implement, and deploy its new network protocols or cooperation schemes without disturbing other running protocols

  21. Virtualization, the enabler • Properties • Isolation • Fault, software and performance isolation • Encapsulation • All VM state can be captured into a file • Interposition` • All guest actions go through monitor • Monitor can inspect, modify, deny operations • PlanetLab, OneLab, XORP, etc.

  22. Security, Internet Achille Heel’s • What should be in future Internet security • strong encryption and authentification ? • VPN’s Proxies ? • Secure routing ?

  23. Future Internet minimal security • A secure execution environment • A code should be executed the way it is designed and not differently • An authentication mechanism • Local of global authentication ? • Monitoring • Interposition layer ?`

  24. Scalability or the delusion of grandeur

  25. Q(x,y) key Compact space routing y • d-dimensional space with n zones • 2 zones are neighbor if d-1 dim overlap • Routing path of length: • Algorithm: Choose the neighbor nearest to the destination (x,y) Peer Q(x,y) Query/ Resource • Fundamental question • Is it possible to design a compact space routing for any application ?

  26. Policies Monitoring Security Enabling continuous deployment of New architectures First applied to Test-beds federation IP world Federation Virtualized substrate

  27. Vision – The « Facility » framework

  28. Experimentally driven research • Why? • Research driven by Intuition & Experimentation + validation • A Playground for enabling new architectures • Shorter time to System/Market • Complementary to Network Science • What? …Enforce a Federation effort on building a large-scale facility for “Internet” research • Building, Operating, Maintaining a testbed is costly • Diversity and scale • Lower the entry cost for experimentation

  29. Conclusions • Two main positions • Future Internet should be polymorphic • Enable the coexistence of different networking paradigms in the same framework • Virtualisation is a key enabler • Future Internet needs a networking science • To have strong foundations rooted in • Physics, information theory, economics, sociology, ethnology, etc… • Cooperation is a strong concept

  30. Conclusions • Issues • To develop this networking science • Flexibility • Virtualization is key • We are moving toward a “no architecture” • Security • Sandbox, authentification and monitoring should be integrated to architecture • Scalability • Is it possible to construct infinitely scalable addressing and routing schemes • Clean Slate approach should enable the coexistence of different addressing/routing schemes.
