An energy management system within a building obtains energy usage data over several cycles to determine a minimum feasible load. The minimum feasible load corresponds to operational conditions of the building, such as occupied or unoccupied. The energy usage data is binned according to the operational condition under which it was obtained. A threshold based on the minimum feasible load is used to monitor energy usage within the building and to identify anomalies in energy demand for possible action.

The rate at which packets are provided to a cryptographic engine of a cryptographic system is adjusted using a feedback mechanism to increase the output of the cryptographic system. Data is classified and queued on a per class/flow basis and stored in input queues prior to being processed. A class based queue scheduler is implemented to select data from the input queues to be transmitted to the cryptographic engine. The cryptographic engine operates in processing cycles. At each cycle, an amount of data is transferred from the input queues to a cryptographic engine input queue. A cryptographic accelerator in the cryptographic engine processes the data on the cryptographic engine input queue during the cycle. The output rate of the cryptographic accelerator is measured during the cycle and this value is used as feedback to determine how much data should be passed to the cryptographic engine for a subsequent cycle.

A method and an apparatus that reduce the burden on routers by removing the aggregation and physical Wide Area Network (WAN) interface functions from the router are provided. The aggregation and physical Wide Area Network interface transparently forwards traffic and routing information to and from the WAN without becoming a router. The disclosed forwarding technique and apparatus is applicable to IP protocol as well as other protocols. As provided, the routing device is connected to a forwarding device via the Local Area Network (LAN) and the IP Multiplexer forwards data packets to one or more physical WAN links.
