11:45-12:30 Keynote 1: 5G QoS Meets Cloud Networking

Room Magnólia, Chair: Prosper Chemouil

Abstract: 5G Networks will launch a new innovation era of enterprise and industrial automation through the use of edge computing. The distributed edge computing platform is a crucial component of the 5G innovation ecosystem. Emerging 5G services will require high bandwidth, ultra-reliability and low latency. Delivery of these services will require more than just compute and storage from the cloud platform. It is essential to have a secure, dependable highly available network that is adaptive and is an integral part of the application development platform. 3GPP has defined network slicing as a key feature of 5G networks. Network slicing requires orchestration of both compute and network resources from the radio to the core to meet the stringent demands of 5G services. This talk will explore how cloud networks can address the QoS needs of 5G services.

11:00-11:45 Keynote 2: 6G architecture challenges: how to build a fully automated and cloud-friendly mobile network

Room Magnólia


Abstract: This talk tries to make some assumptions on the KPI requirements of the coming 6G mobile networks and describe the main challenges, with a strong focus on architecture and simplification. So far the mobile architecture was quite similar from generation to generation as a main result of the stability of the requirements: the strict (law-enforced) guarantees needed for voice communication and the (so far) quite stable end-to-end transport protocols used for reaching the servers on the Internet. But things are changing: cloud-based implementations can simplify the architecture even if the requirements don’t change drastically. And requirements might change too: Internet protocols have evolved significantly, emerging new use cases are coming - with potentially quite different communication patterns. So maybe it is time to reevaluate some of the seemingly very old and stable assumptions and design a simpler, easy to manage mobile architecture.

11:00-11:45 Keynote 4: 6G meets future networking

Room Magnólia


Abstract: While the deployment of 5G is ongoing, research towards the next generation mobile communication namely 6G has started recently. Next to novel radio concepts, 6G is expected to have a major impact on the way we operate networks, in particular. This presentation starts with opportunities and challenges of emerging networking paradigms such as in-network computing and programmable networks and puts them in a 6G context. Their contribution to meet the strict requirements for end-to-end 6G communication will be discussed. For 6G, we also see new paradigms taking a major influence on networking and we will elaborate on the role of AI and digital twin for future networking. Examples from ongoing research projects illustrate the findings and are a basis to derive further research challenges and opportunities.

Abstract: This talk outlines the user landscape and technologies driving the evolution of networking to a cloud centric world. We describe the key aspects of cloud-native networking where all network functions are composed of cleanly disaggregated {data,control,management} planes. We highlight some of the desirable properties such as formal verification, massive scale emulation, progressive roll-out, roll-back and roll-forward in the event of anomalous behavior, and intent-driven automation.
