SCPS-TP, TCP, and Rate-Based Protocol Evaluation
Overview Tests were performed at Glenn Research Center (GRC) to validate the operation of Space Communications Protocol Suite-Transport Protocol (SCPS-TP) relative to the Consultative Committee on Space Data Systems (CCSDS) specification, to perform a comprehensive comparison of SCPS-TP protocol options to IP based protocols, and to determine the implementation maturity level of these protocols - particularly for higher speeds. The testing was performed over reasonably high data rates of up to 100 Mbps with delays that are indicative of near-planetary environments. The tests were run for a fixed packet size, but for various errored environments. The results indicated that SCPSTP congestion-friendly options perform slightly better than TCP SACK protocols at moderate and high error-rates whereas IP rate-based protocols performed slightly better than SCPS-TP rate-based options.
