The present invention relates to an arrangement and a method for flow control of data packets in a communications system supporting communication of packet data. The arrangement comprises classifying means (1) for, by means of a number of parameters defining a number of data packet subflows, whereby each received packet belongs to one of the subflows. For each received data packet, an individual packet holding time is given by the size of the data packet and by the (desired) bandwidth of the subflow to which the packet belongs. It further comprises first queueing means (2) comprising one subflow queue (SFQ) for each subflow, such that received data packets are placed in the appropriate subflow queue, and one or more second queueing means (3), each comprising a circular timeslot array register, wherein for each timeslot a timeslot queue (TSQ) is provided. Data packets from the subflow queues are placed in the appropriate time slot queues in relation to a current time slot queue, the packets in which, if any, currently being output, such that the data packet holding times can be observed. |
