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.
