Title: FSA: Fronthaul Slicing Architecture for 5G using data plane programmable switches

Abstract: 5G networks are gaining pace in development and deployment in recent years. One of 5G’s key objective is to support a variety of use cases with different Service Level Objectives (SLOs). Slicing is a key part of 5G that allows operators to provide a tailored set of resources to different use cases in order to meet their SLOs. Existing works focus on slicing in the frontend or the C-RAN. However, slicing is missing in the fronthaul network that connects the frontend to the C-RAN. This leads to over-provisioning in the fronthaul and the C-RAN, and also limits the scalability of the network. In this talk, we will present the design and implementation of Fronthaul Slicing Architecture (FSA). FSA runs in the switch data plane and uses information from the wireless schedule to identify the slice of a fronthaul data packet at line-rate. It enables multipoint-to-multipoint routing as well as packet prioritization to provide multiplexing gains in the fronthaul and the C-RAN, making the system more scalable.

Title: Demystifying Key Technologies of Future of 6G Networks

Abstract: The development of the sixth generation of wireless communication technology is currently underway and is expected to be introduced before 2030s. There are various concepts and technologies that are still being explored, including the use of higher frequencies and wider bandwidths, the discovery of new applications, and the investigation of spectrum optimization through artificial intelligence and MIMO technologies. One of the most buzzed-about aspects of 6G networks is the Open Radio Access Network (ORAN), which is a groundbreaking idea that offers an open-source platform that brings together multiple vendors and allows for seamless integration of different network elements. This means that there is greater flexibility and scalability in selecting vendors and controlling network infrastructure, leading to reduced costs and streamlined operations.

In this presentation, we will be sharing with you NI’s perspective on cutting-edge 6G technologies and a range of successful user cases from around the globe. Through our insights and real-world demonstrations, we aim to offer you valuable insights into the latest advances in this exciting field, as well as concrete examples of how these technologies are being leveraged to drive sustainable growth and innovation in diverse sectors and markets.
