IPv6 has been around for twenty years, but the fundamentals had not evolved much. As cloud and overlay have become more important, system designers have not had to give much thought to the addresses themselves.
However, as large-scale, low-power IoT becomes more prevalent, IPv6 becomes more important due to its simplicity, auto-configuration capabilities and scalability. In addition, new routing extension headers such as SRv6 have recently been defined to enable Network Programming and expand the range of IPv6 applications.
This tutorial will introduce the evolution of IPv6, especially in the IoT context, and actual IoT deployments. Then, we will cover the SRv6 overview, and examine SRv6 as a form of IPv6 evolution. Finally, Softbank, the SRv6 lead operator, will talk about SoftBank’s initiatives on SRv6.

Pascal Thubert, Principal Engineer, Cisco Systems
Pascal Thubert has been actively involved in research, development and standards efforts on Internet mobility and wireless technologies since joining Cisco in Y2K. He currently works at Cisco’s Chief Technology and Architecture office, where he focuses on products and standards in the general context of IPv6, wireless, and the Internet of Things. He co-chairs 6TiSCH, the IETF Working Group focusing on IPv6 over the 802.15.4 TSCH deterministic MAC, and LPWAN, that applies IETF protocols over low power wide area networking technologies. Earlier, he specialized in IPv6 as applied to mobility and wireless devices and developed routers and switches microcode in Cisco’s core IPv6 product development group. In parallel with his R&D missions, he has authored multiple IETF RFCs and draft standards dealing with IPv6, mobility and the Internet of Things, including NEMO, 6LoWPAN and RPL.
