Abstract
ATM network comprises an ATM cross connect network for connecting local switches to each other, and a signalling network including a plurality of transit switches each having a bandwidth management function to manage the bandwidth allocation of a prescribed link in the ATM cross connect network. By transmitting the control signal from an originating local switch to a destination through successive transit switches of the signalling network, a required bandwidth is allocated to a virtual channel of the ATM cross connect network. ATM cells are transmitted between the two local switches through the established virtual channel.
