The High-Level Architecture (HLA) provides a common
architecture for distributed modeling and simulation. In its original
form the HLA allows a number of simulations to be joined together into
a federation using a single run time infrastructure. Recently there
has been an interest in joining multiple such federations together
using a mediating unit, called an HLA "bridge." This document
presents an in-depth study of the feasibility of an HLA bridge in
the context of the current HLA interface specification. The results
are summarized on two levels. First, we identify general classes of
problems and solutions. Second, we provide a detailed discussion of
the desired behavior of selected service protocols in the presence of
a bridge federate.
