Abstract:
1. A packet switch, comprising: N input buffer sections, provided for respective N input lines, for storing unicast packets and multicast packers input through corresponding input lines; a switch section for outputting a unicast packet to any of M output lines to which the unicast packet is transmitted when the unicast packet is input from each of the N input buffer sections, and outputting the multicast packet to a plurality of M output lines to which the multicast packet is to be transmitted when the multicast packet is input; and a scheduler section for selecting the unicast packet or the multicast packet to be output from each of said N input buffers such that the input lines and the output lines cannot conflict each other for the unicast packet, and such that the input lines cannot conflict each other for the multicast packet, wherein the scheduler section excludes a plurality of destination output lines of the multicast packets from a target of conflict control in a scheduling process for the multicast packets performed by the scheduler section.
