A SATELLITE ASYNCHRONOUS TRANSFER MODE MATCHING APPARATUS FOR TRANSFERRING AN INTERNET AND A VIDEO DATA TO SATELLITE NETWORK AND THE MATCHING METHOD THEREOF

摘要

PURPOSE: A satellite ATM(Asynchronous Transfer Mode) interface device for transmitting Internet and video data to a satellite network and a method therefor are provided to multiplex ATM data, the Internet data, and the video data of a terrestrial network, which have inter-different traffic characteristics, and transmit the multiplexed data to a satellite. CONSTITUTION: A line interface unit(100) synchronizes a received frame or packet, and transmits a generated corresponding frame or packet to an ATM network, an Internet network, and a transmission network. A cell/frame processing unit(200) receives the frame or packet transmitted from the line interface unit(100), and generates an ATM cell or processes a valid cell and generates a new frame. A FIFO processing unit(300) receives and stores the ATM cell generated from the cell/frame processing unit(200), and grasps states of one or more FIFOs. A multiplexing/demultiplexing process unit(400) receives state grasp result values of the FIFOs from the FIFO processing unit(300), multiplexes the ATM cells according to the characteristic of a traffic, and transmits the multiplexed ATM cell. The multiplexing/demultiplexing process unit(400) demultiplexes a cell received from the outside, and transmits the demultiplexed cells to the FIFO processing unit(300).
