ATM COMMUNICATION SYSTEM WITH ATM CELL COMPRESSION/ DECODING FUNCTION, NODE DEVICE WITH ATM CELL COMPRESSION FUNCTION AND NODE DEVICE WITH ATM CELL DECODING FUNCTION

摘要

PROBLEM TO BE SOLVED: To effectively utilize a communication line by transmitting a compressed ATM cell and allowing a receiver side to decode the ATM cell so as to suppress a transmission capacity in the system. ;SOLUTION: In the case that communication data such as image data are given to a transmission node device 2, an ATM cell assembly section 21 applies ATM cell assembling to the communication data. An ATM cell obtained by the ATM cell assembly section 21 is compressed by an ATM compression processing section 22 and an ATM cell transmission section 23 transmits the compressed ATM cell to a reception node device 3 via a communication line 4. An ATM cell reception section 31 in the reception node device 3 receives the compressed ATM cell that is being transmitted via the communication line 4, and an ATM cell decode processing section 32 decodes the cell. That is, the transmission node device 2 compresses the ATM cell to be sent and transmits the cell and the reception node device 3 decodes the ATM cell compressed by the transmission node device 2 into the cell in the original state to reduce a data quantity sent through the communication line 4.;COPYRIGHT: (C)2000,JPO
