2118592 9305596 PCTABS00020 Reactive congestion control in an asynchronous transfer mode (ATM) network where the network is formed by the interconnection of nodes each including a forward path (8-OF, 8-2F, 8-(C)F) for transfer of information from source (4-(S)) to destination (4-(D)) through the network and a return path (8-(C)R, 8-(C-1)R, 8-1R, 8-OR) for returning congestion control signals. Each source includes a modifiable issue rate unit which issues forward information signals at different rates for virtual channels in response to the presence and absence of congestion signals received on the return path. A segmentation communication unit segments packets into a plurality of cells concurrently for a plurality of channels for transmission over the ATM network. A reassembly communication unit reassembles cells received from the ATM network concurrently for the plurality of channels. Pipelined processing units are employed for segmentation and for reassembly.
