transmitted by both sides. The controlling application simply has priority over the passive
application. From a performance point of view, the controlling application should be the one

Figure 1 on page 44 is a symbolic representation of the hierarchies in the definition of this
communication structure. It is not drawn to scale to reflect the scope of the individual sub-
descriptions. Depending on the particular network structure, the definition of the connec-
tions between the applications can be much larger than the definition of the applications.
