Variable length data switch and a variable length data relaying method using the variable length data switch

A variable length data switch comprising:

• a receiver side cell line configuring unit having a fixed length data receiving means for receiving fixed length data from a fixed length data line and a receiver side data converting means for converting said received fixed length data into variable length data;
• a variable length data switching unit for switching the variable length data from said receiver side cell line configuring unit;
• and
• a variable length data transmitting unit for transmitting the variable length data from said variable length data switching unit to a variable length data line.

A variable length data relaying method using a variable length data switch comprising the steps of:

• switching variable length data received from a variable length data line, converting the variable length data into fixed length data, transmitting said converted fixed length data to a fixed length data line in a first variable length data switch comprising a variable length data receiving means for receiving variable length data from the variable length data line, a variable length data switching unit for switching the variable length data from said variable length data receiving means, and a transmitter side cell line configuring unit having a transmitter side data converting means for converting the variable length data form said variable length data switching unit into fixed length data and a fixed length cell transmitting means for transmitting said fixed length data converted to said fixed length data line;
• performing a cell relay of the fixed length data from said first variable data switch on the basis of a protocol of an upper layer;
• and
• converting the fixed length data relayed in the cell relay into variable length data, switching said variable length data and transmitting it to a variable length data line in a second variable length data switch comprising a receiver side cell line configuring unit having a fixed length data receiving means for receiving fixed length data from a fixed length data line and a receiver side data converting means for converting said fixed length data received into variable length data, a variable length data switching unit for switching the variable length data from said receiver side cell line configuring unit and a variable length data transmitting means for transmitting the variable length data from said variable length data switching unit to said variable length data line.
