Deploying Scalable and Stable XDP-Based Network Slices Through NASOR Framework for Low-Latency Applications

Abstract

The spreading and popularization of applications such as Artificial Intelligence (AI), the Internet of Things (IoT), and Virtual Reality (VR) have relentlessly changed the way we live and communicate. Besides, these applications, having specific requirements that transcend connectivity, have changed the way they have reserved the underlying resources. In this sense, to satisfy these applications agreeably, network slicing mechanisms are needed to make it possible to customize connectivity for applications that run on generic network hardware through a separate data and control plane. Besides, connectivity needs to be responsive to vertical business requirements, such as low-latency and high-reliability. This paper proposes the XCP Controller, a scalable and stable method of configuring data planes for network slices between multiple Internet domains for applications with low-latency requirements. Empirical results suggest that the combination of NASOR and XCP Controller enables to deploy network slices over early packet processing technologies to experience lower latencies than other baseline technologies.
