Incremental Path-Selection and Scheduling for Time-Sensitive Networks
Industrial real-time applications demand their communication networks be robust and reliable so that packets are delivered with bounded delay and jitter. The IEEE Time-Sensitive Networking (TSN) Task Group has amended the standards of IEEE 802.3 Ethernet to support time-triggered flows of real-time applications. However, the issues of routing and scheduling are left as open problems. Majority of the state-of-the-art scheduling efforts make some assumptions, such as assuming that the routing information is known a priori and focusing on addressing the scheduling problem or assuming that the flows’ information is known in advance. Other studies that avoided these assumptions ignore some valuable information that could be used in the routing decision such as the residual bandwidth. In this paper, we first propose an incremental QoS-aware path selection algorithm that uses QoS measurement to route TSN flows. Then, we introduce multiple incremental scheduling algorithms that address these issues, and demonstrate their performance.
