4 Geneva, Switzerland, 18 February Internet Architecture Model Very successful for almost 30 years Connecting almost everything Flexible On top of many links Low speed, high speed, variable latencies Large variety of applications File transfer, streaming, voip,…

5 Few protocols Geneva, Switzerland, 18 February Steve Deering The Evolution of Layered Protocol Stacks Leads to an Hourglass-Shaped Architecture Saamer Akhshabi, Constantine Dovrolis Sigcomm 2011

6 Internet Protocol Interoperability, But ossification. Geneva, Switzerland, 18 February Steve Deering

7 IP is: Geneva, Switzerland, 18 February IP Packet Format -Management -Interoperability -Forwarding Addresses -Allocation -Display -Routing P A R P 4 ≠P 6 A 4 ≠A 6 R 4 =R 6

8 New areas for Networking Internet of Things Cheap Moore’s law reduces costs, does not increase power Low Memory Low Energy Different Time cycle Legacy devices 20 year lifetime Geneva, Switzerland, 18 February 20148

9 IPv6 IPv6 slowly introduced P6≠P4, A6≠A4: No interoperability Metcalfe’s law against IPv6 Forwarding is not the most difficult part IPv6 has advantages for IoT Auto-configuration Simpler Layer 2 agnostic But difficult to make IPv6 evolve Geneva, Switzerland, 18 February 20149

10 Constraints Geneva, Switzerland, 18 February IoT Deployed IPv6 6LoWPAN Header Compression M-U capabilities Fragmentation P 6LP = P IPv6 A 6LP = A IPv6

11 ARESA2 Project ANR Verso 2009 project Urban Wireless Sensor Networks AMI, Smart Grid, M2M... One of the challenges: IPv6 Mesh network. Minimize code footprint, minimize energy consumption. Geneva, Switzerland, 18 February

12 Reduce 6LoWPAN impact Toward a flexible 6LoWPAN Simplify addresses allocation A 6LP ⊂ A IPv6 Forwarding based on 6LoWPAN Add functionalities for WSN P 6LP ⊃ P IPv6 Maintain end to end capabilities Need for “local” information IPv6 remains universal format Multi-homing Geneva, Switzerland, 18 February

13 6LoWPAN in Contiki Geneva, Switzerland, 18 February

14 Example Geneva, Switzerland, 18 February

15 Architecture Geneva, Switzerland, 18 February IPv66LoWPAN Extension IPv6 6LoWPAN + parameters

16 Conclusions and Recommendations New constraints: A single protocol cannot cover all needs Introduce more flexibility “a la IEEE” Core protocols/Fringe protocols Other alternatives: REST, but less generic in term of traffic Geneva, Switzerland, 18 February

17 Reasearch on IoT at Télécom Bretagne OCIF research team: Architecture: Internet evolution, REST, M2M, Access Network: NAN, Long Range Radio, community network,… Context Awareness: Security, … Models: Game Theory, Peak Erasing,… Application domains: ITS, SmartGrid, Smart Clothes,… Geneva, Switzerland, 18 February
