End-to-End Performance Guarantee for Distributed Real-Time Embedded Systems

This paper proposes an Integrated Control Algorithm (ICA) for the Distributed Real-Time Embedded Systems (DRES) that employs the end-to-end aperiodic task model. ICA features a distributed feedback loop that relates the per-task metric to the aggregate metric. It is able to dynamically determine the QoS (Quality of Service) of incoming tasks and guarantee the end-to-end deadlines of accepted tasks, at the same time enforce the desired utilization bound on multiple processors. Finally, experiments demonstrate that ICA is capable of providing better performance guarantees for DRES that employs the end-to-end aperiodic task model.
