A constant voltage/constant power AC adapter converts AC voltage to DC voltage to provide power to a plurality of loads. The adapter's output characteristic is approximately a constant voltage as long as the output current draw by the loads is less than a threshold (e.g. a safety threshold for the adapter). If, however, the power draw on the adapter is such that the output current exceeds the threshold, the adapter then decreases its output voltage to maintain the power draw at a safe level. One or more loads that draw power from the adapter may be adapted to detect a drop in the AC adapter's output voltage. When such a voltage drop is detected, that information tells the load that too much current is being drawn from the adapter and that the load should throttle back (e.g., reducing battery charge current, CPU clock frequency, display brightness, etc.).

A universal gateway that allows data to be transferred between one or more network protocols and one or more control protocols is described. The various protocols can coexist on the same physical network medium or on separate networks. The gateway also provides tunneling of network protocols through a selected protocol, and centralized control of network nodes. By using the gateway, end-users can mesh together traditionally standalone, incompatible, networks into a universally accessible, centrally administered, “super-network.” The gateway provides a centralized node database, support for legacy protocols, a rules engine, and an object-oriented class library interface. Configuration is simplified through automatic device discovery. The centralized node database is managed by an active server node. High reliability access to the centralized node database is enhanced by the system fault tolerance provided by standby server nodes. When used in connection with a power line network, the gateway provides the ability to distribute various types of data streams over the power line. Routing handlers provided by the gateway allow virtually any of the legacy data networking services such as TCP/IP to be routed over the power-line.
