Performance of space communication protocol standards (SCPS) over ACTS satellite links

Space communication protocol standards (SCPS) has been developed for the reliable transfer of information in the future space and interplanetary Internet. Some work has been done on performance evaluation of SCPS by testing it over the low-rate channels and/or via an emulation test-bed. However, this work has been done by testing SCPS over the low rate channels and/or via an emulation test-bed. It is expected to have an evaluation of the complete SCPS protocol suite in a realistic space environment with a large bandwidth-delay product (BDP). In this paper, we present an experimental performance evaluation of SCPS suite, by comparing with standard TCP/IP, over the NASA's Advanced Communications Technology Satellite (ACTS) high speed links with data rate up to 4 Mb/s.
