摘要

In a switch provided on a network for transferring data, a switch unit (120, 220) includes a scheduler (122, 222) for setting a switch core (121, 221) and an input port unit (120, 220) includes a data allotting unit (111) for allotting transfer data on a priority basis, buffers (112) provided corresponding to the priorities for temporarily storing and outputting the allotted transfer data, a request aggregating unit (113, 211) for aggregating connection requests related to transfer data which are allotted on a priority basis, allotting the connection requests in accordance with the priorities which are taken into consideration in processing by the scheduler and outputting the obtained requests, and a data aggregating unit (115) for aggregating transfer data output from the buffers and transmitting the aggregated data to the switch core (121, 221).
