Figure 138 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 makes use of the GID component, and the
state machines associated with the operation of GID, in order to control
its protocol interactions.
