Adaptive resource management architecture for distributed real-time embedded systems
Ke Liang, Xingshe Zhou, Ruiqing Sheng, Kailong Zhang · 2009
Avionic distributed real-time embedded (DRE) systems execute in open environments where operational conditions, input workload, and resource availability cannot be characterized accurately a prior. We present adaptive resource management architecture for these systems to achieve end-to-end QoS. The architecture contains two loops and adopts bottom-up philosophy to deal with workload/resource variations. The inner loop is established based on feedback control theory, and handles mild variations; while the outer one includes subtask allocation and migration algorithms, to cope with drastic variations.
