GARP architecture is shown in Figure 34.
Figure 34. GARP Architecture
The GARP application component of the GARP participant is responsible
for defining the semantics associated with the parameter values and
operators received in GARP PDUs, and for generating GARP PDUs for
transmission. The application uses the GID component, and the state
machines associated with the operation of GID, in order to control its
protocol interactions.
An instance of GID consists of the set of state machines that define the
current registration and declaration state of all attribute values associated
with the GARP participant. Separate state machines exist for the applicant
and registrar. This is shown in Figure 35.
