Abstract:
An ATM cell compression device in an ATM cell compression recovery system, said ATM cell compression recovery system comprising: an ATM cell recovery device including a compressed cell determination unit that determines whether an ATM cell inputted from an opposite ATM cell compression device through a transmission line is a compressed cell, and a cell recovery unit that, when the compressed cell determination unit determines that the ATM cell is a compressed cell, applies a recovery processing to the ATM cell in an ATM layer to recover the compressed cell into a first original ATM cell; a switch device that applies a switching processing to the ATM cell recovered by the ATM cell recovery device; and an ATM cell compression device including a compression object cell determination unit that determines whether the ATM cell outputted from the switch device toward an identical path is a compression object cell, and a compressed cell production unit that, when the compression object cell determination unit determines that the ATM cell is the compression object cell, applies a compression processing to the ATM cell in an ATM layer to produce a compressed cell.
