<p>A method for transmitting packets or cells (or both) in a communications network (10) is disclosed. The packets or cells are transmitted along a forward communications path in a network from a source node (h1) via one or more intermediary nodes (r1, x1, r5 and r2) to a destination node (h4). At the intermediary nodes (r1, x1, r5 or r2), the packets or cells are received in a buffer (38 or 42-1 to 42-4). The packets or cells are transmitted along the forward communications path according to a communications schedule. In the presence of congestion at one of the intermediary nodes (x1), an indication of the congestion (302-342) is provided to the destination nodes (h4) of the first packets to be transmitted according to the schedule. An indication of the congestion of the first packets or cells is provided by the destination nodes (h4) of the first packets or cells to the source nodes (h1) of the first packets or cells via a feedback communications path.</p> |
