ABSTRACT:
A multicasting method transmits data segments, including one or more data packets, over an established global multicast tree from a Sender S to a dynamically changing set of receivers, including at least one unknown Receiver R. In response to a data segment transmission, the Sender S receives a first status signal from the at least one unknown Receiver R (and/or any known Designated Receivers DRs) indicating the addition of and packet reception status of the unknown Receiver R (and/or any known Designated Receivers DRs) which has joined the multicast. In response to the status signals, the Sender S retransmits to the unknown Receiver R (and/or any known Designated Receivers DRs) those packets not received thereat. In this manner the unknown Receiver R (and/or any known Designated Receivers DRs) is added to the multicast session and retransmissions thereto are handled in the same manner as other receivers connected to the multicast session.
