Abstract

A network management device which registers for any state change notifications from the devices in the network. The network management device updates its status and values of the devices associated with each state change notification by querying the device. In this manner the management device can make a more timely update for a particular device and need not keep querying devices that have not changed, thus eliminating many unnecessary transactions. In certain embodiments polling is still performed. As a result, the management device is both more current in its displayed data and has fewer network transactions.
