1. A method for delivering data packets from a source node to a plurality of end-system nodes in a multicast overlay network tree with scalable group communication throughput and end-to-end reliability, the method comprising:

  • providing at least one backup buffer in each one of a group of end-system nodes in the multicast network tree;

    storing copies of data packets transferred from an input buffer to an output buffer in one of the group of end-system nodes in the backup buffer;

    sizing the back-up buffer in accordance with maximum sizes of the input and output buffers and a number of simultaneous end-system node failures to be accommodated in the multicast overlay network; and

    preventing data packet losses between end-system nodes in the multicast overlay tree using communication protocols or backpressure mechanisms.
