#### Keynote1: Reliable and Available Wireless: The IPv6 contribution towards end-to-end determinism over 5G and beyond

#### Abstract

Deterministic Networking is an attempt to emulate the properties of a serial link over a switched fabric, by providing a bounded latency and eliminating congestion loss, even when co-existing with best-effort traffic. It is getting traction in various industries including professional A/V, manufacturing, online gaming, and SmartGrid automation, enabling cost and performance optimizations (e.g., vs. loads of P2P cables). Bringing determinism in a packet network means eliminating the statistical effects of multiplexing that result in probabilistic jitter and loss. This can be approached with a tight control of the physical resources to maintain the amount of traffic within a budgeted volume of data per unit of time that fits the physical capabilities of the underlying network, and the use of time-shared resources (bandwidth and buffers) per circuit, and/or by shaping and/ or scheduling the packets at every hop. This innovation was initially introduced on wired networks, with IEEE 802.1 Time Sensitive networking (TSN) for Ethernet LANs, and is being extended over Wi-Fi and 5G. This talks goes through the parallel efforts at the IETF by the DetNet and RAW working groups, where RAW extends DetNet to provide high reliability and availability for IP connectivity over a wireless medium.

#### Biography

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.

#### Keynote2: Reconfigurable Intelligent and Holographic Surfaces for Wireless Communications

#### Abstract

A Reconfigurable Intelligent Surface (RIS) is a planar structure that is engineered to have properties that enable the dynamic control of the electromagnetic waves. In wireless communications and networks, RISs are an emerging technology for realizing programmable and reconfigurable wireless propagation environments through nearly passive and tunable signal transformations. RIS-assisted programmable wireless environments are a multidisciplinary research endeavor. This presentation is aimed to report the latest research advances on modeling, analyzing, and optimizing RISs for wireless communications with focus on electromagnetically consistent models, analytical frameworks, and optimization algorithms. In addition, the interplay between RISs and holographic surface-based transceivers will be discussed with focus on near-field communications in line-of-sight channels.
