The integration of holographic technologies is fundamentally changing the landscape of interactive applications. It enables for instance applications such as holographic concerts with remote participants fully immersed in concert rooms with performers on stage. A myriad of new applications can be contemplated. Volumetric media delivery is the cornerstone of all these applications. However, its key requirements (I.e. low latency and high bandwidth) cannot be fully met by the current network infrastructure. In-Network Computing (INC) stipulates computing insides the network instead of computing on servers outside the network for tackling latency and bandwidth challenges. The fundamentals date back to the 90s and there is now a resurgence due to recent technical developments such as programmable data planes, and P4 programming language. This talk introduces first volumetric media (with holographic media as illustration) and the requirements on network infrastructures. The basics of INC are then discussed along with the principles for application to volumetric media delivery. A case study on holographic concert is presented third and we end the speech by sketching the research directions.


Roch H. Glitho (M’88–SM’97) received the M.Sc. degree in business economics from the University of Grenoble, Grenoble, France, M.Sc. degrees in pure mathematics and computer science from the University of Geneva, Geneva, Switzerland, and the Ph.D. degree (Tech.Dr.) in tele-informatics from the Royal Institute of Technology, Stockholm, Sweden. He is a Full Professor at Concordia University, Montreal, QC, Canada and an Extraordinary Professor with the Computer Science Programme, University of Western Cape, Cape Town 7535, South Africa. He holds the Ericsson / ENCQOR Senior Industrial Research Chair on Cloud and Edge Computing for 5G and Beyond at Concordia University, and has held a Canada Research Chair in End-User Service Engineering from 2010 to 2020 at the same University. He has performed research, development and product management in industry and has held several senior technical positions, such as a Senior Specialist, a Principal Engineer, and an Expert with Ericsson, Stockholm, Sweden, and Montreal, QC, Canada. Dr. Glitho has served as the Editor-in-Chief for the IEEE Communications Magazine and IEEE Communications Surveys and Tutorials. He has also served as an IEEE Distinguished Lecturer.
