\begin{abstract}

Enterprise distributed real-time and embedded (DRE) systems can
benefit from dynamic management of computing and networking resources
to optimize and reconfigure system resources at runtime in response to
changing mission needs and/\-or other situations, such as failures or
system overload.  This paper provides two contributions to the study
of dynamic resource management (DRM) for enterprise DRE systems.
First, we describe a standards-based multi-layered resource management
(MLRM) architecture that provides DRM capabilities to enterprise DRE
systems.  Second, we show the results of experiments evaluating our
MLRM architecture in the context of a representative enterprise DRE
system for shipboard computing.
