摘要： A technique is provided for managing VPN packet flows over shared access data networks. Each node in the shared access network typically has an identifier or ID associated with it which is used at a Head End of the shared access network to uniquely identify that particular node from the other nodes in the network. According to the technique of the present invention, the node ID may be used at the Head End of the network to identify not only the corresponding node, but also to identify any virtual private networks (VPNs) of which the corresponding node is a member. Using the technique of the present invention, nodes which are members of the same VPN within a shared access network may exchange packets in a manner which does not require the packets to be routed outside the shared access network.

摘要： A power conservation apparatus having a power inlet for providing power to the power conservation apparatus and an external appliance, a power outlet operable to be connected to the appliance, a relay coupling the power inlet and the power outlet, a current sensor operable to measure a current flow from the power outlet to the appliance, a threshold detector operable to receive an input in accordance with the current flow and operable to determine if the appliance is in a state of non-use, and a timer having a set-point; wherein the timer is activated upon the appliance entering the state of non-use and wherein the relay is opened upon the timer reaching the set-point, so as to prevent the power conservation apparatus and the appliance from drawing power from the power inlet. When in the “off” state, the AC power consumed by the apparatus and coupled appliances is zero.
