Connecting several control units via a network is becoming important for a rising number of complex embedded systems. In such systems, each control unit is specialized to execute certain functionality. With the introduction of reconfigurable hardware (commonly FPGAs) as a centric part of the control units, a new dimension of flexibility can be implemented with the help of runtime reconfiguration . On a node level, this includes reconfiguring hardware and software tasks on a single control unit, called ReCoNode in the following, while the reconfiguration may also involve a network level where tasks are migrated among different ReCoNodes of a so-called ReCoNet . An example of a ReCoNet is depicted in Fig. 4.1a. The capability of reconfiguring a ReCoNode or a ReCoNet allows the system to automatically adapt to environmental changes, including faults, network topology changes, or varying workload scenarios, as illustrated by the different examples in Fig. 4.1a-e.
