Abstract:
1. A relaying apparatus comprising: input side accommodating portions including input side queues, a plurality of output side accommodating portions respectively including output side queues, and a switch fabric for mutually connecting the input side queues and the output side queues in a mesh form, each of the input side accommodating portions including; output side-addressed queue managers provided corresponding to each output side accommodating portion as a destination which select, upon a selection of a bandwidth guaranteed packet or a bandwidth non-guaranteed packet, the bandwidth guaranteed packet so as to guarantee a bandwidth, and which output a priority/non-priority signal for indicating which of the bandwidth guaranteed packet and the bandwidth non-guaranteed packet has been selected, and an output demand signal for demanding an output of the selected packet, and an inter-output link manager which, in a time slot of a fixed period, selects any of the output side-addressed queue managers in which a corresponding output side accommodating portion as a destination has an empty area in its priority queue when the output demand signal is outputted and the priority/non-priority signal indicates priority, or selects any of the output side-addressed queue managers in which a corresponding output side accommodating portion as a destination has an empty area in its non-priority queue when the output demand signal is outputted and the priority/non-priority signal indicates non-priority, for outputting a packet selected by the output side-addressed queue manager.
