a Subsystem. Different Subsystems can contain devices with the same name, however.
For example, a building may consist of a Subsystem object for each room, with each room
Subsystem including AppDevice object s called VAV and Thermostat.
The NetworkServiceDevice class provides a logical representation of the OpenLNS Server
and its NSI. The network service device, in turn, contains a NetworkInterface object.
This network interface determines the driver name to be associated with the system, if
any. Many additional object classes are provided to OpenLNS applications through the
Object Server.
