Abstract: PURPOSE: A method for transmitting reliable multicast data for processing continuous media is provided to supply a reliable multicast protocol for processing the continuous media capable of processing multi media data with dynamic group managements according to a system capacity of a remote computer, so as to prevent services from being suspended because of data losses, and to improve service quality to make the remote computer supply same multicast services. CONSTITUTION: A reliable multicast protocol forms groups on the basis of process usage rates in a kernel of a remote computer, and stratifies the groups. The protocol decides whether changes of the process usage rates are generated in kernels of each remote computer. If so, the protocol dynamically changes the groups. The protocol transmits data by group units, and simultaneously decides whether a data non-receiving signal is inputted from a receiving side. If so, the protocol reads non-receiving data parts to store the read parts in a buffer. The protocol transmits the non-receiving data parts to each local session by using a user level real-time scheduling policy.
