/**
* <!-- begin-user-doc -->
* A representation of the model object '<em><b>Node</b></em>'.
* <!-- end-user-doc -->
*
* <!-- begin-model-doc -->
* Node represents the computer nodes of the embedded EE system. Nodes consist of processor(s) and may be connected to sensors, actuators and other ECUs via a BusConnector.
*
* Node denotes an electronic control unit that acts as a computing element executing Functions. In case a single CPU-single core ECU is represented, it is sufficient to have a single, non-hierarchical Node.
*
* Semantics:
* The Node element represents an ECU, i.e. an Electronic Control Unit and an allocation target of FunctionPrototypes.
*
* The Node executes its allocated FunctionPrototypes at the specified executionRate. The executionRate denotes how many execution seconds of an allocated functionPrototype´s execution time that is processed each real-time second. Actual execution time is thus found by dividing the parameters of the ExecutionTimeConstraint with executionRate.
*
* Example: If an ECU is 25% faster than a standard ECU (e.g., in a certain context, execution times are given assuming a nominal speed of 100 MHz; Our CPU is then 125 MHz), the executionRate is 1.25. An execution time of 5 ms would then become 4 ms on this ECU.
*
* Notation:
* Node is shown as a solid-outline rectangle with Node at the top right. The rectangle contains the name, and its ports or port groups on the perimeter.
