Abstract
An ATM cell compression recovery device includes an ATM cell recovery device having a compressed cell determination unit that determines whether an ATM cell from a transmission line is a compressed cell, a cell recovery unit that recovers the determined compressed cell in an ATM layer into an original ATM cell, and a switch that switches the recovered ATM cell. The ATM cell compression recovery device also includes a compression object cell determination unit that determines whether ATM cells received from the switch on an identified path have been compressed, and a compressed cell production unit that compresses the ATM cell in an ATM layer to be transmitted on the identified part. With this device, data is compressed and recovered in the ATM layer of the ATM network.
