Reaching the end of Moore’s law: challenges in cloud networking
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
Head of Ericsson Research
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.
