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.
