Claim Text:
1. A method, comprising: receiving, at an aggregating node in a network, feedback messages from one or more destination nodes in the network, the destination nodes being designated to receive data as packets from a source node using rateless coding, wherein the feedback messages indicate whether packets are needed at a corresponding destination node to complete the data; determining, from the feedback messages, an amount of packets needed by each of the corresponding destination node; calculating and storing a maximum amount of packets needed by a single destination node; aggregating the feedback messages into a single aggregated message, wherein the aggregated message is a single integer that represents the maximum amount of packets needed at any one of the one or more destination nodes, wherein the maximum amount of packets is indicated in the aggregated message only when a difference between a greatest amount of packets needed by a single destination node and a least amount of packets needed by a single destination node is less than a threshold value; and transmitting the aggregated message toward the source node.
