Abstract:
1. A method of transmitting, over an ATM network, data flows generated in accordance with a connected mode transport protocol and formatted in packets in accordance with a non-connected mode network protocol, each packet containing a source address and a destination address, the method comprising the steps of: assigning, in advance, a set of virtual circuits of the ATM network to each pair of access points of the ATM network without allocating transmission rate resources to said virtual circuits; when a first access point of the ATM network receives a request, formulated in accordance with said connected mode protocol, to establish a connection between a source address and a destination address accessible via a second access point of the ATM network, selecting an available virtual circuit from the set assigned to the pair comprising said first and second access points of the ATM network and transmitting on the selected virtual circuit an ATM resource management cell containing a message requesting activation of the selected virtual circuit; when said ATM resource management cell is received by a node of the ATM network located on the selected virtual circuit, assigning a transmission rate resource, if available, to the selected virtual circuit.
