Abstract: PURPOSE: A method and an apparatus for differentially providing quality of a service of multicast are provided to make a user feel the transmission delay of the packet less by adjusting a packet transmission time by corresponding to a receiving target number of packets. CONSTITUTION: A packet monitoring unit(103) senses the transmission and reception amount of packet of different nodes, and a delay time selector(101) sets up a maximum delay time by corresponding to the reception amount. The delay time selection unit selects the delay time at random within the range of maximum delay time. If the delay time is 0, a packet transmitter(102) transmits the packet. If the packet is not transmitted from another node, a delay time controller(104) decrease the delay time every time.
