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.

翻译：本白皮书展示了2021-2022年REDMARS2项目的部分研究成果，探讨了将递归互联网架构（RINA）概念整合至容迟与中断容忍网络（DTN）协议的方法。通过采用Bundle-in-Bundle封装（BIBE）技术，我们实现了基于作用域的分离机制，从而构建了可扩展的DTN系统。本工作的核心贡献在于展示了基于BIBE的实际应用案例，包括涉及无人机（UAV）与卫星中继的太阳系互联网真实通信场景。在与欧洲空间局（ESA）合作开展的实地测试支持下，评估结果证实了BIBE作为可扩展、递归且互操作的DTN架构基础技术的可行性。
