Abstract
Method and apparatus for supporting the Asynchronous Transfer Mode (ATM) connectionless service by means of Partial Connections (PCs) in an ATM system (18). These PCs are established between the source users (10, 11, 17) of said ATM system (18) and the destination switching nodes (14) to which the destination users (15) are linked. The use of PCs has no constraints on the size of the domain, because the information the source user (10, 11, 17) inserts in the Virtual Path Identifier/Virtual Channel Identifier (VPI/VCI) field of ATM cells to be transmitted to a destination user (15), is local to the source switching node (12) to which the source user (10, 11, 17) is connected. The information inserted in the VPI/VCI field identifies the PCs along which ATM cells are to be routed.
