An increasing number of DRTS (Distributed Real-Time Systems) are employing an end-to-end aperiodic task model.The key challenges of such DRTS are guaranteeing utilization on multiple processors to achieve overload protection,and meeting the end-to-end deadlines of aperiodic tasks.This paper proposes an end-to-end utilization control architecture and an IC-EAT (Integration Control for End-to-End Aperiodic Tasks) algorithm, which features a distributed feedback loop that dynamically enforces the desired utilization bound on multiple processors.IC-EAT integrates admission control with feedback control, which is able to dynamically determine the QoS (Quality of Service) of incoming tasks and guarantee the end-to-end deadlines of admitted tasks.Then an LQOCM (Linear Quadratic Optimal Control Model) is presented.Finally,experiments demonstrate that, for the end-to-end DRTS whose control matrix G falls into the stable region, the IC-EAT is convergent and stable.Moreover, it is capable of providing better QoS guarantees for end-to-end aperiodic tasks and improving the system throughput.
