Abstract: A power distribution and control system is provided, comprising: a power input configured to receive current from a vehicle battery; a plurality of switches, each switch operable to control current from the power input to one of a plurality of vehicle circuits; a communications interface; a memory operable to store the programming commands received through the communications interface; and a processor operable to, in response to the immediate commands and the programming commands stored in the memory, selectively control each of the plurality of switches. The communications interface is operable to: receive immediate commands from an external electronic device; receive programming commands from an external electronic device; and transmit circuit status information to the external electronic device.

Abstract: Protocols and architecture for secure virtual private networks. Intraenterprise data communications are supported in a secure manner over the Internet or other public network space with the implementation of secure virtual private networks. Members of a virtual private network group exchange data that may be compressed, encrypted and authenticated, if the exchange is between members of the group.

Abstract: An N-way bridging system for local area networks (LANs) through which a source routed frames are transmitted, is based on hardware filtering in bridge ports responsive to the input LAN and bridge identified in the source routed frame, independent of the output LAN identified in the source routed frame. This filtering forwards the frame to the bridge host processor if a match on the input LAN and bridge number is detected. The host then reads the output LAN parameter from the frame and determines the appropriate routing. This technique preserves the hardware filtering of the IBM Source Routing specification for token ring LANs at least in part, and is assisted by the bridge host processor in determining the output port on the bridge.
