Abstract

This whitepaper presents parts of the results of the REDMARS2 project conducted in 2021-2022, exploring the integration of Recursive Internetwork Architecture (RINA) concepts into Delay- and Disruption-Tolerant Networking (DTN) protocols. Using Bundle-in-Bundle Encapsulation (BIBE), we implemented scope-based separation mechanisms resulting in scalable DTNs. A key contribution of this work is the demonstration of practical BIBE-based use cases, including a realistic Solar System Internet communication scenario involving unmanned aerial vehicles (UAVs) and satellite relays. The evaluation, supported by field tests in collaboration with the European Space Agency (ESA), confirmed the viability of BIBE as a foundation for scalable, recursive, and interoperable DTN architectures.
