Utilization-Based Schedulability Analysis for Switched Ethernet Aiming Dynamic QoS Management

Ethernet switches are typically found in many largescale distributed real-time systems providing low-end transactions as well as bulk backbone routing to realtime applications. The FTT-SE protocol (Flexible Time-Triggered communication over Switched Ethernet) is a recent proposal to bypass the limitations of conventional switches in terms of real-time behavior while catering for growing requirements on dynamic reconfigurability and adaptability. For this end, this paper develops linear timecomplexity and memory-efficient on-line admission control tests based on utilization bounds for Rate-Monotonic and EDF scheduling on Ethernet switches using FTT-SE, which are suited for dynamic Quality of Service (QoS) management.
