Asynchronous Time-Sensitive Networking for Industrial Networks

Time-Sensitive Networking (TSN) is expected to be a cornerstone in tomorrow's industrial networks. That is because of its ability to provide deterministic quality-of-service in terms of delay, jitter, and scalability. Moreover, it enables more scalable, more affordable, and easier to manage and operate networks compared to current industrial networks, which are based on Industrial Ethernet. In this article, we evaluate the maximum capacity of the asynchronous TSN networks to accommodate industrial traffic flows. To that end, we formally formulate the Flow Allocation Problem (FAP) in the mentioned networks as a convex mixed-integer non-linear program. To the best of the authors' knowledge, neither the maximum utilization of the asynchronous TSN networks nor the formulation of the FAP in those networks have been previously addressed in the literature. The results show that the network topology and the traffic matrix highly impact on the link utilization.
