Abstract
Disclosed are a method and a system for transmitting a message or data packet from a single sender (21) to a plurality, i.e. a group of receivers, usually called multicasting, within a conventional unicast transmission network, i.e. a network basically not equipped to handle such multicast transmissions, consisting of a plurality of subnetworks (22-24). The nodes or gateways (25-29) connecting the subnetworks maintain tables of multicast receiving stations (or groups of such) and the header of each message includes information defining the groups of the addressed multicast receiving stations.
