“…Another interesting future research direction is to adapt the recon iguration mechanisms that have been developed in this study to the interactions between TSN and ifth generation (5G) wireless communication systems that operate with Ultra-Reliable Low-Latency Communication (URLLC). A few recent studies have begun to explore the use of TSN in the 5G URLLC context, see e.g., [28,45,52,71], indicating signi icant potential for improving 5G URLLC services by exploiting TSN. The TSN recon iguration mechanisms developed in this study can poten-tially help in lexibly providing high-quality 5G URLLC services for varying traf ic dynamics.…”

As new networking paradigms emerge for different networking applications, e.g., cyber-physical systems, and different services are handled under a converged data link technology, e.g., Ethernet, certain applications with mission critical traffic cannot coexist on the same physical networking infrastructure using traditional Ethernet packet-switched networking protocols. The IEEE 802.1Q Time Sensitive Networking (TSN) Task Group is developing protocol standards to provide deterministic properties, i.e., eliminates non-deterministic delays, on Ethernet based packet-switched networks. In particular, the IEEE 802.1Qcc, centralized management and control, and the IEEE 802.1Qbv, Time-Aware Shaper (TAS), can be used to manage and control Scheduled Traffic (ST) streams with periodic properties along with Best-Effort (BE) traffic on the same network infrastructure. We investigate the effects of using the IEEE 802.1Qcc management protocol to accurately and precisely configure TAS enabled switches (with transmission windows governed by Gate Control Lists (GCLs) with Gate Control Entries (GCEs)) ensuring ultra-low bounded latency, zero packet loss, and minimal jitter for ST TSN traffic. We examine both a centralized network/distributed user model (hybrid model) and a fully-distributed (decentralized) 802.1Qcc model on a typical industrial control network with the goal of maximizing the number of ST streams.

Safety-critical traffic in Industrial Internet of Things (IIoT) requires real-time communications with high fault tolerance, bounded latency and low jitter. Time-Sensitive Software-Defined Network (TSSDN), which combines the deterministic transmission of Time-Sensitive Networking (TSN) with the centralized management of Software-Defined Networking (SDN), was recently proposed to support the real-time requirement in IIoT. The research on TSSDN has been receiving increasing interests, however, the existing work has limitations including 1) the functional safety of TSSDN cannot be guaranteed; and 2) the effect of the separation of data plane and control plane on the time-sensitivity of TSSDN has not been evaluated. Therefore, in this paper, we employ the timed model checker UPPAAL to formalize the TSSDN architecture. Firstly, we use the build-in checker in UPPAAL to verify deadlock-free property, functional safety property and starvation-free property of our model. Then, the total latency of frames forwarding and scheduling within a single switch is measured based on the model. We focus on the latency overhead of frames requesting processing rules from the controller, which is on average an additioanl 180µs latency in the worst case, but the impact of this delay on the time-sensitivity of TSSDN is tolerable. As far as we know, this is the first paper providing a formal verification and analysis approach for TSSDN architecture, which could benefit for both TSSDN designers as well as the researchers.
