Cross-Domain Network Slicing for Industrial Applications

Abstract

Building on virtualization and programmability, 5G networks aim for concurrent support of application domains with different functional and QoS requirements, both across and within vertical domains. Towards these requirements, network slicing mechanisms allow the management and orchestration of the underlying pool of resources, typically within a single administrative domain. However, in several occasions, verticals are expected to have a large geographical footprint, often crossing the administrative borders of multiple network domains, placing a subsequent functional requirement for cross-domain orchestration. In this paper we describe our approach on cross-domain sliciNg operations for the case of Industrial Applications with strict and flexible QoS requirements, with a particular focus on Wind Power plant networks. We describe the design of our SDN-based orchestration TRL-7 prototype and further provide a detailed look on the testbed prepared for measurements in an operational Wind Power plant in Brande, Denmark.
