Abstract
Systems and methods for automatically controlling efficient operation of a plurality of network appliances operatively linked and networked to balance network traffic load across a plurality of network appliances that are selectively enabled. The system facilitating performance of the method includes at least a plurality of network appliances operatively connected to a switch and controlled by a network access control module. During system operation, at any given moment in time, the plurality network appliances operate in one of two modes, fully operational or stand-by. The network appliances of the plurality that are fully operational and thereby consuming full operational power depends upon the network traffic load at any given moment in time. The network appliances functioning in a stand-by mode consume low power levels which are sufficient to allow a network appliance in stand-by mode to receive a command signal directing it to switch from stand-by to full operational mode.
