ABSTRACT:
Management of the activity status of flows in a packet-switched telecommunications network is disclosed. For each packet received belonging to the flow, the location of a flow register in a data structure is determined from an identifier of the flow. An activity status of the flow is determined from an activity credit in the determined flow register. The flow is considered inactive if the activity credit has expired. An updating process progressively and simultaneously reduces the activity credits of the active flows, so that if a flow that has been determined active does not receive a packet during at least the time-out period, the credit of the flow expires at the end of the time-out period.
