IPv6 ND was designed for P2P and transit subnetworks with cheap and reliable broadcast capabilities. This session will explain how this is unfit with IoT wireless operation, and explain the operation of SFAAC (stateful address autoconfiguration) that was introduced with 6LoWPAN ND.
The talk will discuss how SFAAC interacts with RPL and proxy ND to build scalable multi-link subnetworks, where the L3 concepts of Link and Subnet are not necessarily congruent with the layer 2 broadcast domain.
Pascal Thubert has been actively involved in research, development, and standards efforts on Internet mobility and wireless technologies since joining Cisco in 2000; he currently works at Cisco’s Chief Technology Office. Standards-wise, Pascal mostly contributes to the ETSI and the IETF. At the IETF, he co-chairs two IoT-related Working Groups and contributes to several others in the Internet and routing areas, where he authored 20+ RFCs the general context of IPv6, wireless, and the Internet of Things; he also contributed to the creation of DetNet and RAW and participates to the IEEE/IETF coordination, the INT Area and the IoT directorates. Pascal holds an Engineering Degree from the Ecole Centrale de Lyon and a Ph.D. from IMT Atlantique, and above 300 patents.
