Internetworking Asynchronous Transfer Mode With The Consultative Committee For Space Data Systems Advanced Orbiting Systems Protocols

Future space missions will require the integration of voice, video and data communications at increasing speeds and reduced costs. Both manned and un-manned missions may use the NASA/JPL Deep Space Network (DSN), which consists of two segments, the space segment and the ground segment. The space segment will use Consultative Committee for Space Data Systems (CCSDS) Advanced Orbiting Systems (AOS) protocols which end at the DSN ground stations. These protocols have been designed with the intended channel being a space segment. The ground based segments may use the emerging standard for broadband communications of integrated services called Asynchronous Transfer Mode (ATM). ATM has been designed with the intended channel being optical bre. Thus the integration of the space segment with the ground network poses various implementation issues. The issues addressed here are the possible methods for integrating CCSDS AOS with ATM.
