SYSTEM AND METHOD FOR DATA TRANSMISSION BASED ON MULTICAST

摘要

PURPOSE: A multicast based data transmission system and method thereof are provided to embody reliable multicast functions by preventing duplicated data transmission. CONSTITUTION: A representative reception apparatus(200) receives multicast data transmitted by a transmission apparatus(100). After the multicast data is received, the representative reception apparatus transmits a data reception complete state. The representative reception apparatus confirms a data receivable state. The transmission apparatus repetitively transmits the multicast data to a multicast group until data reception complete state of the representative reception apparatus is confirmed.
