Considering the significant success of the terrestrial Internet, the National Aeronautics and Space Administration (NASA) and other space agencies have been working for a few decades to enable space communications using the Internet-type protocols such as transmission control protocol/ Internet protocol (TCP/IP), namely, space internetworking or simply(More)
Delay/disruption tolerant networking (DTN) is considered one of the most suitable technologies for implementing a space system of systems (SoS) internetworking architecture. Aggregation of multiple DTN bundles within a data transport block, which was proposed to resist space channel asymmetry, has been a controversy for years. In this paper, an experimental(More)
