Abstract
A system for forming one point-to-multipoint connection provides various service attributes in an ATM network in response to differences in service attributes requested by receiving parties or differences in available resources. A network node sets up an output VC (Virtual Channel) link to be connected to an input VC link, the VC links being parts of a point-multipoint connection, receives a new VC link set-up request, and adds to the point-multipoint connection, in response to the new VC link set-up request, new output VC link with service attribute different from that of the input VC link.
