Abstract: A system and method for analyzing network power consumption is disclosed. The system and method for analyzing network power consumption includes the steps of specifying at least one service which will run on said network; defining a plurality of resources provisioned in the network, each having an associated power efficiency; associating a network path with the service; calculating a sum of the power efficiencies for the resources of the network path; and outputting the sum to a display device. The system and method for analyzing network power consumption is particularly useful for identifying power consumption efficiencies throughout a communication network.

Abstract: An add/drop arrangement using broadband optical couplers provides a low-loss, highly flexible add/drop capability for survivable wavelength division multiplexed (WDM) ring networks. At each node in the ring having the broadband optical coupler-based add/drop element, a portion of optical signal power of the entire WDM signal (i.e., all optical channels) is tapped off so that one or more optical channels of particular wavelengths can be dropped at the node. Information (e.g., data) to be added at the node is supplied in an optical channel that is added to the WDM signal via the broadband coupler. Because the add/drop element uses a broadband coupler, another portion of optical signal power of the WDM signal, including any added optical channels, passes through the node onto the ring. Depending on the specific ring topology being used with the broadband coupler-based add/drop arrangement, additional wavelength assignment and handling measures may be required.
