SHAPING CIRCUIT

摘要

PURPOSE:To provide a shaping circuit reducing a hardware quantity by separating ones which need shaping processing from ones which do not in an ATM network so as to execute shaping processing concerning only the ones which need shaping processing. CONSTITUTION:A judging circuit 1 compares the reported parameter of an user and a judging condition regulated on the side of the network so as to judge whether to execute shaping processing about connection concerning the reporting parameter. A processing objective cell separation circuit 2 separates the shaping processing objective ones from each cell in an input cell current in accordance with the judging result of the judgement circuit 1. A shaping part executes shaping processing to only the shaping processing objective cells. Then, a cell multiplex circuit 32 multiplies the output cell of the shaping part and the shaping processing objective cell from the processing objective cell separation circuit 2.
