    • In a switching network with a plurality of inlets and outlets and a plurality of interconnected switching nodes having inputs and outputs with respective addresses, a method is described of modifying a first set of outlets to which a cell stream is routed from one of the inlets to a second set of outlets to which this cell stream is to be routed, the addresses of the outputs of each switching node from which the cell stream is output being stored in a routing table of the node. The method includes the steps of transmitting a modification request message to the inlets from each outlet belonging to one but not to both sets and in each switching node receiving the modification request message on one of its outputs, selectively transmitting the request message to the inlets or transmitting a confirmation message to the above each outlet depending on the absence or presence in the node routing table of addresses of node outputs other than the one node output, respectively.

    • An ATM network, in which the downward data rate, from the network to the users, is greater than the upward data rate, from the users to the network. Multiplexers are provided for establishing connections, constituting virtual channels, between users and the network; the virtual channels are grouped into virtual paths. In each multiplexer close to the user, the bandwidth allocated to each downward virtual path is variable under the control of a call control means provided upstream in a switching node, and the upward virtual channels have a fixed bandwidth. Preferably, in the downward direction, each virtual channel is assigned a permanent or semi permanent quality of service.
