Multipoint-to-point packet transfer over virtual circuit

摘要

A network (10) comprises a plurality of switching nodes (11(1)-11(6)) interconnected by a plurality of communication links (13(8)-13(16)). At least one virtual circuit is established in the network (10) to at least one terminating switching node (11(n)) defining a path which the other switching nodes (11(n)) can use to transfer message packets to the terminating switching node (11(n)).
