Abstract
A computing device configured for retransmitting lost packets for multicast is described. It includes a processor and instructions in memory. It identifies data, which it begins sending via multicast. No data is resent until all the data has been sent. The computing device requests missed packet lists and waits. It adds missed packets to a map if there are replies. It determines whether there are any missed packets and resends any missed packets. Another computing device for retransmitting lost packets for multicast is described. It includes a processor and instructions in memory. It identifies data for distribution, which it begins sending via multicast. It waits to resend any data until all of the data has been sent. A missed packet indication is requested and received. The computing device updates lists of complete and incomplete target nodes. It determines and sends a peer download instruction.
