Boston, MA: Springer; 2005: 267-277.In highly dynamic scenarios a real-time communication/real-time operating system
(RCOS/RTOS), which can fulfill all upcoming demands of the application,
is normally very extensive. These RCOS/RTOS systems are heavy-weighted and
produce much overhead. System resources for an application or a system service
are often reserved for worst-case scenarios and are not usable for other applications.
We present a self-optimizing RCOS/RTOS with an integrated flexible
resource management. Our RCOS/RTOS adapts its services to the application
demands and redistributes temporarily unused resources to other applications
under hard real-time conditions. The benefit of our system is shown by means
of a self-optimizing communication service. The main building block of this
communication service is a reconfigurable dual-port Ethernet switch. Using dynamically
reconfigurable hardware to implement the switch enables an adaption
of the switch to changing requirements during run-time
