Revisiting fundamental results in Network Calculus for Time-Sensitive Networks reveals overlooked packetization effects and proposes improved delay bounds.
الملخص
The content delves into the application of Network Calculus (NC) in constructing service models and computing delay bounds for Time-Sensitive Networks (TSNs). It revisits basic min-plus service models, highlighting the impact of packetization on analysis. The paper introduces the max-plus branch of NC to handle packetized traffic explicitly, proposing an integrated approach combining min-plus and max-plus models. Detailed discussions on TSN transmission selection algorithms, system models, network calculus basics, and implications of packetization are provided. Various approaches for delay bound analysis are explored, leading to new insights and improved bounds.
