摘要： A multiple multicast network system and method for ensuring reliability in such a network are provided. A multiple multicast method in a multiple multicast network system may include grouping terminals having data to be transmitted to each other in a group. The method transmits, by each of the terminals in the group, data of each of the terminals to the other terminals in the group. In response to receiving the data, the method provides, to the terminals in the group, as feedback, missing packet information, and generates, by a terminal among the terminals in the group, a secondary network-coded packet by performing network coding based on a successfully received packet and data of each of the terminal, and transmits the secondary network-coded packet to the other terminals in the group based on the missing packet information.
