Making Our Networking Stack Truly Extensible

Dr. Olivier Bonaventure

Head of the Group
Department of Computing Science and Engineering
IP Networking Lab
Louvain-la-Neuve, Belgium

ABSTRACT

BPF is a simple virtual machine that was designed to facilitate packet filtering. It was later extended and attached to the Linux kernel where it provides a growing number of useful services. This talk explores how eBPF enables our ossified networking stack to become truly extensible.

The talk starts with a brief description of how eBPF makes IPv6 Segment Routing truly programmable. Then, I explain how with proper eBPF support in the TCP stack, it becomes possible to support new TCP options or modify TCP algorithms using eBPF code that is injected by applications.

I then describe how eBPF can make Multipath TCP much more flexible than it is today. Similar techniques are also applicable for higher layer protocols. I then explain how we added eBPF support to QUIC and used this new extensibility technique to create pluginised QUIC, a variant of QUIC where a server can send over a QUIC connection eBPF bytecode that adds support for new extensions on the client. We used this technique to implement Multipath QUIC, QUIC VPN and add support for Forward Erasure Correction to demonstrate its flexibility. A similar technique has been applied to ToR, BGP and OSPS. The talk ends with a discussion of the architectural impacts of this new approach.

ABOUT THE SPEAKER

Olivier Bonaventure is professor at UCLouvain (Belgium) where he leads the IP Networking Lab. Together with the Ph.D. students and postdocs of the lab, he has contributed to various networking protocols including BGP, LISP, Multipath TCP, IPv6 Segment Routing, and QUIC. He is active within the IETF and the lab has produced open-source implementations of important protocols including Multipath TCP, IPv6 Segment Routing, LISP, and more. He is the current editor in chief of SIGCOMM CCR and the main author of the open-source Computer Networking: Principles, Protocols and Practice e-book. He co-founded the Tessares company that pioneers the deployment of Hybrid Access Networks.

Tactile Internet with Human-In-The-Loop

Dr. Frank H. P. Fitzek

Professor and Head of the "Deutsche Telekom Chair of Communication Networks"
Technische Universität Dresden
Dresden, Germany

ABSTRACT

The talk will address the technology needed to build up the tactile Internet. Main focus is on low latency and ultra-reliable communication and how it can be realized in softwarized networks. Current technologies such as 5G are discussed to enable the tactile Internet. Furthermore, the talk will highlight inter disciplinary research on tactile Internet with focus on phycology and medicine building the required human to machine interfaces to have mutual learning between humans and machines.

ABOUT THE SPEAKER

Frank H. P. Fitzek is a Professor and head of the "Deutsche Telekom Chair of Communication Networks" at TU Dresden coordinating the 5G Lab Germany. He is the spokesman of the DFG Cluster of Excellence CeTI.

He received his diploma (Dipl.-Ing.) degree in electrical engineering from the University of Technology – Rheinisch-Westfälische Technische Hochschule (RWTH) – Aachen, Germany, in 1997 and his Ph.D. (Dr.-Ing.) in Electrical Engineering from the Technical University Berlin, Germany in 2002 and became Adjunct Professor at the University of Ferrara, Italy in the same year.

V2X Networks for Connected and Automated Driving

Dr. Javier Manuel Gozalvez Sempere

Professor and Director, Ubiquituous Wireless Communications Research (UWICORE) Laboratory
Communications Engineering Department
Universidad Miguel Hernández de Elche (UMH)
Elche, Spain

ABSTRACT

V2X (Vehicle-to-Everything) networks will be fundamental for the reliable, scalable and successful deployment and operation of Connected and Automated Vehicles (CAVs). This talk will first discuss why V2X networks are necessary for CAVs, and how they can support advanced cooperative driving (or maneuvering) and perception applications. This includes an overview of current standardization activities, and insights into challenges of cooperative driving and perception. There is currently a lively technical and industrial debate on which V2X technology (IEEE 802.11- or cellular-based) is better suited to support CAVs. The second part of the talk will then analyze the current V2X technologies, their performance, challenges and opportunities, as well as their evolution. The talk will end with a discussion on the need to envision a future heterogeneous V2X ecosystem to effectively support a reliable and scalable deployment of CAVs.
