<p>PURPOSE:To minimize the load or a network due to a multicast response frame with respect to the repeating installation, which relay plural networks and transmission/reception equipments. CONSTITUTION:A multicast frame detecting means 3, a frame storing means 4, and a frame sending means 5 are provided. The multicast frame detecting means 3 receives frames from transmission/reception parts 11 to 1n and detects response frame to transfer it to the frame storing means 4 but transfers the other frames to a repeating processing.part 2. This part 2 sends frames to networks through proper transmission/reception parts 11 to 1n in accordance with their destination addresses. The frame storing means 4 stores response frames; and when a certain condition is satisfied, this means 4 starts the frame sending means 5, and frames of the same destination address out of frames stored in the frame storing means 4 are coupled and are transferred to the repeating processing part 2 as one frame.</p> |
