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 transmission schedule. In the presence of congestion at one of the intermediary nodes x1, an indication of the congestion 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.Other References
