Overview
Figure 35 is a symbolic representation of the hierarchies in the definition of the system. It is not drawn to scale to reflect the scope of the individual sub-descriptions.

Participating host: H1, H2, etc.
Host-specific parameters
R1
R2
etc.
Applications in R1, R2 etc.
Application-specific parameters
A1
A2

Figure 35 The logical hierarchy when defining the communication structure of a system
The communication structure of a system can be depicted by a graph with nodes and edges. The nodes correspond to the applications, while the edges represent the communi- cation channels. The blocks in the diagram define the nodes of the graph with respect to the specific system, host or application. The edges of the graph represent the applications’ connections, with each application connected to all of the other applications.
From the input data (which has already been explained), the configuration generator
