Abstract:
A device for multicast-session management provided in a network including one or more servers and a plurality of clients, comprising:a data-exchange interface which receives an original data flow from a server, and multicasts a multicast data flow to the network; a usable-multicast-address-registration unit which stores therein usable multicast addresses; a destination-address-conversion unit which converts a destination address of the original data flow into a multicast address, the multicast address being selected from the usable multicast addresses stored in said usable-multicast-address-registration unit, wherein said data-exchange interface multicasts the original data flow having the multicast address as the multicast data flow; and wherein the usable multicast addresses stored in said usable-multicast-address-registration unit fall within a multicast-address range assigned to the device, the multicast-address range being different from a multicast-address range assigned to any other devices for multicast-session management provided in the network.
