    • 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 classiffying 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 receied 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.
    • 本发明涉及支持分组数据通信的通信系统中的数据分组的流量控制的装置和方法。 该装置包括分类装置(1),用于通过定义多个数据分组子流的多个参数,由此每个接收的分组属于其中一个子流。 对于每个接收到的数据分组,单个分组保持时间由数据分组的大小和分组所属的子流的(期望的)带宽给出。 它还包括第一排队装置(2),其包括用于每个子流的一个子流队列(SFQ),使得接收的数据分组被放置在适当的子流队列中,以及一个或多个第二排队装置(3),每个包括圆形时隙阵列 寄存器,其中对于每个时隙,提供时隙队列(TSQ)。 来自子流队列的数据分组相对于当前时隙队列(当前正在输出的分组)被放置在适当的时隙队列中,使得可以观察到数据分组保持时间。
