    Abstract: A method to provision routes in a network having a plurality of nodes includes receiving a designation of a primary source node, determining possible destination nodes from the designated source node and outputting information indicating the possible destination nodes. The method further includes receiving a designation of a destination node from among the possible destination nodes and updating information regarding optical characteristics based on a route from the source node to the designated destination node and outputting information related to the updated optical characteristics.

    Abstract: Signals propagating in wavelength division multiplexing (WDM) optical networks suffer from loss, which decreases optical signal-to-noise ratios (OSNRs) and degrades a quality of received transmissions. Present methods of boosting OSNRs involve regeneration using transponders, which scale in complexity with the number of WDM channels. Optical amplifiers may boost signal strength, but amplified spontaneous emission (ASE) noise often reduces OSNR despite increases in signal strength, although changing the amplifier operating settings may reduce emitted ASE noise power. A method or corresponding apparatus in an example embodiment of the present invention provides a planning tool for deploying optical amplifiers in an optical network in a manner that reduces the need for optical regeneration, reducing cost and complexity of the deployed network. In one embodiment, the disclosed planning tool may substitute models of high-gain amplifiers operating at low settings for models of low-gain amplifiers operating at high settings.

    Abstract: A method, apparatus, system, and computer program, for operating a network planning tool. The method includes recognizing at least one predetermined criteria being satisfied or triggered, and learning at least one network attribute, to be used in subsequent network planning. Various types of network attributes can be learned, such as, e.g., network element parameters, site parameters, link parameters, demand parameters, optical parameters, general parameters, and networking parameters. Example attributes may specify, e.g., a maximum number of add/drop channels, at least one alarm threshold, a maximum number of sites per network ring, a maximum number of add/drop sites per ring, and a maximum ring circumference. Others can specify a maximum light path distance, a routing tendency, at least one grooming node, or the like.

    Abstract: Due to demand for more network bandwidth, a need for multi-user optical network topologies has, and will continue to, increase. A method or corresponding apparatus in embodiments of the present invention provide for an availability determination tool for determining and displaying wavelength and subrate availabilities within a network. Benefits of embodiments of a tool include allowing a user to identify the availability and capacity of any wavelength on any network, via an interactive graphical user interface, such as by using three-dimensional representations. In one embodiment, the disclosed availability determination tool allows users to locate and view any combination of available wavelengths between nodes in an optical network topology, and generate graphical and tabular reports of the availability in order to maintain an efficient and organized method or apparatus for determining and controlling wavelengths in a network. Consequently, service providers using the tool can keep performance rates high and costs low.
