  Abstract

The key to the asynchronous traffic shaping (ATS) technology being standardized in IEEE 802.1 time sensitive network (TSN) task group (TG) is the theorem that a class-based FIFO system, attached with a minimal interleaved regulator (IR) does not increase maximum delay while suppress the burst cascade. In this work it is proved that the theorem also holds with a system that is FIFO only to individual flows. Based on the observation that this “flow FIFO system” can be a single network, while the class-based FIFO system is within a single node, it is further suggested that the networks with minimal IRs attached at their output ports, with flow aggregates (FAs) within a network, can guarantee end-to-end delay while drastically reduce the scheduler complexity. Numerical analysis shows that the suggested FA-based system with low complexity yields similar or better performance than the integrated services (IntServ) system with high complexity.
