Edge-, or more generally, In-Networking is a popular topic in networking research today. In fact, networks today include a lot of "computing" already, e.g., CDN overlays networks, application-layer gateways, and Network Functions Virtualization. Recent advances in network dataplane programmability, lessons learned from distributed computing, new applications such as Metaverse-style augmented reality, and observed architectural issues with current overlay in-network computing have motivated the development of Compute-First Networking (CFN) – a principled approach that aims to combine dataplane programmability with distributed systems concepts.
In CFN, we are asking: how can we leverage recent advances in network programmability to provide useful, general-purpose, distributed computing layer, without being constrained by TCP/IP networks and overlay computing platforms? Specifically, we are exploring the potential of optimizing networking and computing resources holistically and the possibility of completely rethinking networking by enabling much greater degrees of programmability at all layers of the system. Potential applications of CFN include IoT Edge Computing, Edge Data Processing, Augmented Reality, Distributed Machine Learning, and principally, the redesign of the current Web/Internet stack.
This talk will describe the real-world motivation for CFN, summarize the state-of-the art in network-programmability, describe key CFN concepts, different CFN research results, specifically the first prototype of a decentralized CFN DataFlow system. The talk will include thoughts on future work, e.g., the potential impact on future network architectures for ubiquitous IoT and Metaverse-style systems.
Prof. Dr. Dirk Kutscher is a professor for computer science and networking at the University of Applied Sciences Emden/Leer, Germany. Dirk's main interests lie in the intersection of distributed computing and networking and in Internet architecture. Recently, Dirk has initiated a new research direction called "Compute-First Networking" towards re-imaging the relationship of networking and computing. Dirk has held leading positions in multiple Future Internet Research projects and is currently serving as the technical director for the Piccolo project, a new European research initiative on in-network computing. He is also the co-founder and CTO of Fluentic Networks, a UK-based startup that develops trusted in-network computing platforms.
Previously he has been the CTO for Virtual Networking and IP at Huawei's German Research Center, the Chief Researcher for Networking at NEC Laboratories Europe, and a Visiting Researcher at KDDI R&D Laboratories in Japan. He is co-chairing two Research Groups in the Internet Research Task Force (IRTF) on Information-Centric Networking (ICNRG) and on Decentralized Internet Infrastructure (DINRG). Dirk has published several IETF RFCs, books, and research publications on Internet technologies. He holds a PhD degree from Universität Bremen, Germany.
