Using standard Internet Protocols and applications in space

This paper uses a layered approach to discuss all aspects of using Internet technologies in space. It starts with the low-level physical, data link and data routing issues related to using Internet Protocols to support basic spacecraft communications. After identifying options for supporting basic datagram delivery in space, the paper describes issues for selecting transport protocols and applications to meet various mission data delivery needs. Information is provided throughout the paper to identify key implementation issues and provide information on the current status of products in each area. Finally, current implementation and usage of these protocols in both spacecraft and ground systems are discussed.
