Method for Transmission Data for Multicast Based Network, Method for Processing Data and Data Transmission System

摘要

A method for transmitting data for a multicast-based network, a method for processing the data, and a system for transmitting the data are provided to prevent unnecessary time delay by not requiring a retransmission process due to loss of data. A method for transmitting data for a multicast-based network includes the steps of: generating a data packet encoded with an FEC(Forwarding Equivalence Classes) method by a transmitter mode(S1); transmitting the encoded data packet(S2); grasping the loss of the data packet generated on each received path of relay nodes installed on a transmission path of the transmitted data packet(S4); restoring the loss when restoration is needed(S6); transmitting the restored data packet to a child node of the relay node(S8); and receiving the data packet transmitted by the relay node corresponding to a parent node of one of the relay nodes.
