ABSTRACT:
A shaping apparatus comprising a plurality of buffer memories allocated for different flows, bandwidth control units associated with the buffer memories, and a read control unit, wherein each of the bandwidth control units issues a first frame output request based on a maximum allowed bandwidth and a second frame output request based on a minimum guaranteed bandwidth, and the read control unit selects a bandwidth control unit to be permitted for frame output execution out of bandwidth control units that are issuing the first or second frame output request, giving priority to the second frame output request.
