Abstract

The present invention relates to multicasting in an ATM based public data network. Multicasting can be defined as the ability to send a single message to multiple recipients at different locations. A method of multicasting, of the present invention, operates in a packet switched data transmission system typically an ATM broadband data service system. A data packet, intended for transmission to a plurality of addresses, is copied at each node of the system to which one, or more, subscribers, to which said data packet is addressed, are connected. A copy of said data packet is transmitted to each addressed subscriber and to adjacent nodes to which addressed subscribers are connected. This procedure is continued until all addressed subscribers have received a copy of the data packet.
