Abstract:
1. A packet switching equipment for switching packets between input ports and output ports, comprising: input buffer portions temporarily storing packets arriving to said input ports, adding labels identifying destination port numbers to said packets, and outputting packets with the added labels; a switch core portion for switching said packets on the basis of the labels added by said input buffer portions; an arbiter portion providing output permissions to the input buffer portions for outputting to said output ports; and a sorting network autonomously sorting and concentrating said packets on the basis of said labels added to said packets being applied to said switch core portion, wherein said arbiter portion executes an output destination adjusting process for providing output permission for outputting to said output ports for said input buffer portions storing said packets with avoiding overlapping, and a vacant port adjusting process assigning idle output ports not occupied by any input buffer portions for idle input buffer portions not obtaining output permission.
