Node Bundle Scheduling: An Ultra-low Latency Traffic Scheduling Algorithm for TAS-Based Time-Sensitive Networks

Qian Yang, Xuyan Jiang, Wei Quan, Rulin Liu, Zhigang Sun

Abstract: Time Aware Shaper (TAS) and the corresponding traffic scheduling algorithms jointly ensure low-latency and low-jitter data transmission in Time-Sensitive Networking (TSN). However, existing TAS-based traffic scheduling algorithms suffer from either high scheduling failure rate or heavy computation overhead. Such limitations make the algorithms unable to satisfy some TSN applications with harsh scheduling requirements like ultra-low latency and frequent scenarios reconfiguration requirements, such as smart factories in industrial control. Therefore, more efficient traffic scheduling algorithms are required for the specific TSN applications.
