ABSTRACT:
The present invention is directed to the provision of a packet transmission apparatus and, more particularly, to a packet transmission apparatus achieving high-speed processing capability and enhanced relay quality for multicast packets. The packet transmission apparatus comprises: a non-copy packet arbiter which selects one of the non-copy packets by a prescribed algorithm, and requests transmission of the selected non-copy packet; a copy packet arbiter which selects one of the copy packets by a prescribed algorithm, and requests transmission of the selected copy packet; and a final arbiter which selects either one of the transmit requests, the transmit request from the non-copy packet arbiter or the transmit request from the copy packet arbiter, by a prescribed algorithm, and requests transmission of the selected packet, and wherein: the packet transmission apparatus transmits the packet requested by the final arbiter for transmission.
