摘要： Path computation involves determining (120, 930) an aggregate cost for a portion of the path, based at least on the power consumption attributable to use of interfaces along that portion, comparing (130, 930) the portion of the first possible path with a different portion corresponding to a different possible path for the traffic request, based at least on their respective aggregate costs, and selecting (140, 930) which portion to use for the traffic request based on the comparison. Having path selection influenced by the power consumption values, can lead to lower overall consumption in operation than relying only on optimizing nodes individually without regard to how the nodes are used. Path selection can take into account indications of which parts are in a power down mode, and can involve powering up such parts if needed.

摘要： A switching node for an optical communication system has an electrical switch, coupled to switch electrical signals from an input converter to a selected one of the outputs, and has a framer for reading or writing optical transport overhead information from or to the electrical signals. A bypass path is provided so that at least some of the signals being switched can bypass the framer. This can enable each node to be more efficient or handle more signals, since the framer no longer has to process all the signals. A reduction in power consumption can result. A method of configuring the switching node can involve a management system receiving information about the network, determining a new wavelength routing configuration and sending control signals to the node to configure the switches and control which signals use the bypass path.

摘要： A received signal level is controlled in a node used in a point to multi-point (PmP) radio-communication system having microwave time division multiple access (TDMA). Local node control is activated by an AGC in the receiving node, and simultaneously, a radio control loop is activated from the receiving node to each terminal regulating each terminal's transmitted power level. The receiving node AGC reconfigures quickly and is both accurate and stable.
