SAT01-6: Performance Evaluation of Space Communication Protocol Standards (SCPS) over Asymmetric ACTS Satellite Links

Space Communication Protocol Standards (SCPS) has been developed for the reliable transfer of information in the space Internet. There is a need to have an evaluation of the SCPS protocol in a realistic space environment with a large bandwidth- delay product (BDP). An experimental evaluation of SCPS-TP was done by transferring user files using the SCPS protocol over the NASA´s Advanced Communications Technology Satellite (ACTS) links. However, the user files were so small that the steady performance of the protocol could not be accurately evaluated. This paper describes an experimental evaluation of SCPS-TP over high-speed, asymmetric space links by transferring a large user file over asymmetric ACTS link, leading to its steady performance.
