  • Patent number: 11552858
    Abstract: Systems and methods include obtaining a network state of a network having a plurality of nodes interconnected by a plurality of links and with services configured between the plurality of nodes on the plurality of links; utilizing a reinforcement learning engine to analyze the services and the network state to determine modifications to one or more candidate services of the services to increase a value of the network state; and, responsive to implementation of the modification to the one or more candidate services, updating the network state based thereon. The modifications can include changes to any of routing, modulation, and spectral assignment to the one or more candidate services.

  • Patent number: 10298356
    Abstract: Partial optimization systems and methods of wavelengths or spectrum in an optical network include, based on current services in the optical network each having a route and wavelength assignment and based on a ratio of services that can be changed in the partial optimization, preforming a first stage optimization to determine which of the current services are changed for one or more of the route and the wavelength assignment to attain a reduction of a number of wavelengths; performing a second stage optimization to determine an order of implementing changes from the first stage optimization that with the order minimizing one or more of conflicts and step counts; and causing implementation of the changes in the optical network.

  • Patent number: 10009105
    Abstract: Computer-implemented systems and methods for visually presenting spectrum usage of optical spectrum in an optical network include displaying a network map of the optical network comprising a plurality of nodes and a plurality of links connecting the plurality of nodes to one another; responsive to obtaining spectrum data comprising channel assignments on the plurality of links and nodes as endpoints of the associated channel assignments, displaying a plurality of circular histograms to visually illustrate spectrum usage in the optical network; and adjusting the plurality of circular histograms based on selections of a plurality of endpoints in the optical network. The plurality of circular histograms visually represent the spectrum usage by representing the optical spectrum in the optical network around the associated circular histogram, and wherein each portion or segment of the plurality of circular histograms represents one of a wavelength and a portion of spectrum.

  • Patent number: 8447283
    Abstract: A system and method for optimization of media objects for delivery to one of a plurality of mobile communication devices of different types and rendering thereon. In particular, the media objects are optimized according to the mobile device's characteristics to ensure efficient delivery and optimal rendering thereon. For this purpose, an optimized output of the media object is determined at a first stage. At a subsequent stage, based on the mobile device type, the characteristics of the object to be delivered are then adjusted to conform to those of the predetermined optimized output, thus ensuring that the rendering of the optimized media object on the mobile device output is of high quality.
