  • Patent number: 10122443
    Abstract: A technique is provided for determining an optical transmission system description. The technique includes determining a dispersion map of the optical transmission system, placing a set of discrete cumulative dispersions onto the dispersion map, and defining a plurality of sequential system segments of the optical transmission system. Each system segment has an input point that corresponds to a point in the optical transmission system where the input cumulative dispersion matches a cumulative dispersion of the set of discrete cumulative dispersions. For each system segment, an input power of the system segment and a local dispersion value of the system segment is determined. Also, for each system segment, a sequence number of the system segments is stored. Furthermore, for each system segment, the input power and the local dispersion value determined in relation with the input cumulative dispersion of the system segment in a data repository is stored.

  • Patent number: 10117076
    Abstract: Systems, methods, and software that distribute accounting requests to a plurality of Charging Data Functions (CDFs). One embodiment comprises a distributor unit that connects to the CDFs, which register their queues with the distributor unit. When receiving an accounting request (e.g., interim or stop) for a session, the distributor unit extracts an identifier from the accounting request indicating a destination queue previously selected for the session. When the destination queue is not accepting new sessions or ongoing sessions, the distributor unit identifies a prioritized list for the session, identifies a position of the destination queue in the prioritized list, searches the prioritized list for an alternate queue having a lower priority than the destination queue, and having a status indicating that the alternate queue is accepting new sessions. The distributor unit then selects the alternate queue as an alternate destination queue for the session.
