“…We assume that the non-TSN domain is in charge of connecting different TSN domains, and each end station only connects with the TSN domain. There are several candidate technologies for the non-TSN domain, e.g., DetNet [38], Deterministic Dynamic Networks (DDNs) [39], DIP [40], 5G [34], and OpenFlow switches [7], etc.…”

With the rapid development of Industrial 4.0, massive emerging time-critical applications pose new demands for industrial networks, such as strict latency boundaries, ultra-reliable transmission, and so on. Time-Sensitive Networking (TSN) is well suited for these demanding scenarios due to its support for deterministic transmission based on Ethernet. However, many use cases in real industrial scenarios involve non-TSN domains, and, thus, the network requires providing deterministic transmission across non-TSN domains to support them. To this end, this paper proposes a novel Software-Defined Time-Sensitive Networking (SD-TSN) framework that integrates the determinism of TSN and scalability of Software-Defined Networking (SDN). SD-TSN exploits the coordination between the coordinated controller and different domain controllers to bound non-deterministic queuing delays in a way that guarantees determinism. In particular, we designed a multi-domain time-aware traffic scheduling model, which harmonizes the time-aware shaper (TAS) in TSN and time-slots in non-TSN domains based on a global view, generating transmission schedules for each domain. A prototype testbed was built to conduct the experiments. The evaluation results demonstrate that the proposed method can efficiently achieve bounded delay and low delay variations in the transmission across non-TSN domains.

“…Recently, there are studies on scalable deterministic services under the title of LDN (Large Deterministic Networks), based on the technologies of the IETF DetNet Working Group [13][14][15]. These works are based on the CQF technique, which was originally initiated in the IEEE TSN task group.…”

In this work we propose a scalable framework that guarantees both latency and jitter bounds in large networks, including the Internet. The framework is composed of two parts, a latency guaranteeing network and a jitter guaranteeing end system. For latency bounds, we suggest regulators per class per inputoutput port pairs of DiffServ-type relay nodes. For jitter bounds, based on the guaranteed latency bounds, we suggest time-stamping and buffers at the network egress edge. The framework does not require network-wide time synchronization, frequency synchronization, flow state maintenance, or flow level queueing/scheduling. Therefore the complexity does not grow as the number of flows or the network size grows. Moreover, the framework is based on the DiffServ architecture, therefore requires a minimal modification to the current Internet. We show that the proposed regulators can achieve the comparable latency bound to the IEEE asynchronous traffic shaping (ATS) technique. We prove that the jitter is bounded even with realistic limitations such as buffers without cut-through capability. We also prove that under the existence of the clock drift, the jitter still can be upper bounded with a suggested compensation algorithm. We demonstrate with experiments on simple programmable microcontrollers that the jitter upper bound can be within a few tens of microseconds even in a realistic situation with store-and-forward buffers, clock drift, and random network delays.
