Successes and challenges in the Internet architecture

Jari Arkko

Ericsson Research

Despite frequent predictions for its demise, the Internet has proven to be remarkably resilient. Its origins were developed five decades ago, yet it continues to be extremely successful, a key ingredient in our societies’ functions. This talk reviews some of the recent ways in which the Internet is changing and responding to current needs, such the evolution of transport protocols or being able to respond to sudden demand shifts. Such as those occurring due to the 2020 pandemic. The talk goes through some of the reasons that enable this agility. The talk also discusses some of the ongoing stresses and challenges that the Internet faces.

Jari Arkko is a Senior Expert with Ericsson Research. His research focus is on the evolution of Internet technologies, and has worked on security protocols, routers, software development tools, and cellular networks. He has also served as the Chair of the Internet Engineering Task Force (IETF), the Internet technology standards development organization. He likes to personally build and use the technology that he works with. Today he works on Internet evolution and cellular technologies beyond 5G. He is a frequent contributor in matters relating to the Internet architecture, trends, and administration.

Telemetry at Scale and other Challenges in Cloud Networking

Christophe Diot

United States

Google has deployed one of the largest network infrastructures worldwide connecting tens of data centers to billions of users worldwide with a large diversity of workloads (e.g. youtube, search, maps, photos, mobile). A lot of the design principles in the past 20 years was based on Moore’s law. If whether or not Moore’s law has ended is debatable, the fact it will end soon is not and this will impact the way we are designing compute and storage infrastructures. We present the GOOGLE network infrastructure, explain how the end of Moore’s law will impact our design and discuss what the research challenges are for our data centers and networks. We will focus on how telemetry at scale can help us manage always increasing availability requirements in such a massive and growing infrastructure.

Christophe Diot received a Ph.D. degree in Computer Science from INP Grenoble in 1991. Diot pioneered diffserv, single source multicast, epidemic communication, peer-to-peer online games, and most importantly Internet measurements. After INRIA, Diot spent his career in industry, building R&D labs at Sprint, INTEL, Technicolor. He helped launch Safran Analytics as their CTO before joining GOOGLE in june 2018 where he deals with telemetry at scale in cloud infrastructure. Diot has around 40 patents and 300 publications in major conferences and journals. He is an ACM fellow.

The technology Journey towards 6G

Magnus Frodigh

Head of Ericsson Research
Kista, Sweden

Today the network platform is the center of the intelligent digital infrastructure offering endless possibilities to individuals, enterprises, and governments worldwide. We have gone through a paradigm shift where the smartphone has become our primary internet device. With the rollout of 5G the network platform will enable robust new solutions to a wide range of social, environmental, and economic challenges. Still, we are only at the beginning of new journey where the strong technology trends we see today will take us into a very exciting future, towards a next paradigm shift. We could view that as the 6G era.
The internet of senses is one example what we see in front of us, a future where we will use all five senses (sight, hearing, smell, taste and touch) in communication over large distances. Real-time machine communication is another area that is developing quickly, heading towards AI embedded machines everywhere, and AI-to-AI communication may very well dominate the traffic of future networks.
Transitioning toward a world where the internet of senses is a reality and AI is embedded in machines and robots everywhere will rely heavily on the existence of highly capable network platform. The robust 5G network platform that already exists today continues to evolve in such a way that it will be able to deliver the kind of extreme performance required by application areas such as the internet of senses and communication among intelligent machines. Our research suggests that increasingly advanced technologies in four areas – limitless connectivity, pervasive network compute fabric, trustworthy infrastructure and cognitive networks – will play a critical role in the journey towards 6G.

Magnus Frodigh joined Ericsson in 1994 and over the past three decades he had the opportunity to work with the latest technologies in one of the most interesting fields in the industry, leading to the current use of mobile broadband in almost everything we do.
Quoting from his webpage: “To be part of this development and to work on the technology used by so many people is truly inspiring.
He enjoys sharing his knowledge of the telecommunications industry and regularly deliver keynote presentations about topics such as 5G, IoT and future technologies. He’d welcome the opportunity to speak at future events and to connect with those working in academia or the wider Information and Communication Technology (ICT) industry who share a similar passion for research.
He holds a Master of Science degree from Linköping University of Technology, Sweden, and a Ph.D. in Radio Communication Systems from the Royal Institute of Technology, where he has also been adjunct Professor in Wireless Infrastructures since 2013.

On Some of My Simple Results

Leonard Kleinrock

Los Angeles, USA

Often researchers solve problems correctly, but fail to extract the essence and meaning of their own results. In this presentation, we discuss a few of the simple solutions that have come out of the presenter’s research career, focusing on the understanding and intuition that emerges from their simplicity.

Professor Leonard Kleinrock is Distinguished Professor of Computer Science at UCLA. He developed the mathematical theory of packet networks, the technology underpinning the Internet, while a graduate student at MIT in the period from 1960-1962. The birth of the Internet occurred in his UCLA laboratory (3420 Boelter Hall) when his Host computer became the first node of the Internet in September 1969 and it was from there that he directed the transmission of the first message to pass over the Internet on October 29, 1969.
Dr. Kleinrock received his Ph.D. from MIT in 1963. He has served as a Professor of Computer Science at the University of California, Los Angeles since then, serving as Chairman of the department from 1991-1995. He received his BEE degree from CCNY in 1957. and his MS degree from MIT in 1959. He is also the recipient of a number of Honorary Doctorates. He was the first President and Co-founder of Linkabit Corporation, the co-founder of Nomadix, Inc., and Founder and Chairman of TTI/Vanguard, an advanced technology forum organization. He has published over 250 papers and authored six books on a wide array of subjects, including packet switching networks, packet radio networks, local area networks, broadband networks, gigabit networks, nomadic computing, intelligent software agents, performance evaluation, and peer-to-peer networks. During his tenure at UCLA, Dr. Kleinrock has supervised the research for 48 Ph.D. students and numerous M.S. students. These former students now form a core group of the world’s most advanced networking experts.
Dr. Kleinrock is a member of the National Academy of Engineering, a member of the American Academy of Arts and Sciences, an IEEE fellow, an ACM fellow, an INFORMS fellow, an IEC fellow a Guggenheim fellow, and a founding member of the Computer Science and Telecommunications Board of the National Research Council. He is recipient of the 2007 National Medal of Science, the L.M. Ericsson Prize, the NAE Charles Stark Draper Prize, the Marconi International Fellowship Award, the Dan David Prize, the Okawa Prize, the IEEE Internet Millennium Award, the ORSA Lanchester Prize, the ACM SIGCOMM Award, the NEC Computer and Communications Award, the Sigma Xi Monie A. Ferst Award, the CCNY Townsend Harris Medal, the CCNY Electrical Engineering Award, the UCLA Outstanding Faculty Member Award, the UCLA Distinguished Teaching Award, the UCLA Faculty Research Lecturer, the INFORMS President’s Award, the ICC Prize Paper Award, the IEEE Leonard G. Abraham Prize Paper Award, and the IEEE Harry M. Goode Award.
