Support to connectionless services in ATM network using partial connections

摘要

Method and apparatus are disclosed 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, which the source user (10, 11, 17) includes in the ConnectionLess (CL) cells to be transmitted to a destination user (15), is local to the source switching node (12).
