Abstract:
A cell exchanging device which exchanges a plurality of variable length packets multiplexed and packed into one cell to be transferred in an Asynchronous Transfer Mode, comprising:a plurality of receiving interface sections for receiving a cell; a plurality of transmitting interface sections for transmitting the cell; and a switching section for exchanging the cell, to which said receiving interface sections and said transmitting interface sections are connected, wherein: each of said receiving interface section includes a receiving cell transfer control section which disassembles the received cell to demultiplex and unpacked the plurality of variable length packets multiplexed and unpacked in the received cell, and converts the received cell to a cell which has one of the demultiplexd and unpacked variable length packets, thereby transferring the cell to said switching section, said switching section transfers the cell transferred from said receiving interface section to said transmitting interface section where a transmission processing is performed depending on a header value of the cell, and said transmitting interface section includes a transmitting cell transfer control section which demultiplexs and unpacks the variable length packet from the cell transferred from said switching section and multiplexes and packs a plurality of variable length packets in one cell, the plurality of variable length packets corresponding to the same output path.
