However, this equipment constantly consumes electric power, with most of
the energy consumption occurring when no one is present and
the equipment is in an idle state, continuously receiving
network service [1]. The technique of adding a subsystem to
provide proxying for a host system to continue network service
has been studied (Figure 1). By introducing proxying, for
example, maintaining its presence on a network, it is possible
to reduce power consumption, even though the system is in a
