Abstract:
A variable length packet switch which exchanges a plurality of variable length packets loaded on a cell to be transferred in an asynchronous transfer mode, comprising:a receiving interface section for receiving a cell; a transmission interface section for transmitting the cell; and a switching section for exchanging the cell, said switching section to which said receiving and transmitting interface sections are connected, wherein said receiving interface section includes a variable length packet receiving section which disassembles the received cell to demultiplex and unpack the variable length packets multiplexed and packed in the received cell and multiplexes and packs the variable length packets in a cell having the same header value, the variable length packets being transferred to the same transfer interface section where a transmission processing is performed, thereby allowing the variable length packets to pass through said switching section, said switching section transfers the cell transferred from said receiving interface section to said transmission interface section where a transmission processing is performed in accordance with a header value of the cell, and said transmission interface section includes a variable length packet transmission section which disassembles the cell transferred from said switching section, demultiplexes and unpacks the variable length packets multiplexed and packed, and multiplexes and packs the variable length packets to be outputted in the same output path in a transmission cell having the same header value.
