Time-Sensitive Networking on virtualized network components

Academic Paper from the year 2025 in the subject Computer Science - Internet, New Technologies, grade: 1,3, Technical University of Munich, language: English, abstract: Time-Sensitive Networking (TSN) and network virtualization are integral to our modern networking landscape. While TSN enhances Ethernet with mechanisms for deterministic data transmission, network virtualization provides the flexibility and scalability required for rapidly deploying applications. However, their convergence remains a challenging topic. This paper surveys the individual challenges of TSN and network virtualization before deriving issues that complicate the integration of TSN in virtualized networks (e.g., timing, scheduling, and hardware constraints). It also gives an overview of possible synergetic effects of TSN in virtualized environments before concluding with potential research directions that would benefit effective integration.
