Experimental Study of Zero-Copy Performance for Immersive Streaming Service in Linux.

With the development of network technology, many new services are emerging such as virtual reality, Augmented Reality and Holographic-Type Communication. In particular, immersive streaming service demand on the network to satisfy transmission speed, number of device connections and low latency. Even if such an immersive service need ultra-low latency, most of the research focuses on the reducing delay to the network. In other words, in order to satisfy end-to-end ultra-low latency, packet processing in the internal network layer of end devices is important. This paper compares and analyzes the high-speed packet processing technologies such as DPDK and XDP of the network layer in Linux. Our implementation and experiments shows the applicability of each technology with immersive service as an application.
