我们回顾了延迟/中断容忍网络（DTN）架构的当前设计背后的基本原理，并强调了一些悬而未决的问题。它的发展，从深空到更广泛的异构网络，可能会遭受破坏，影响设计决策跨越命名和寻址，消息格式，数据编码方法，路由，拥塞管理和安全。现在已经实现了设计的相对稳定性，需要在长期运行的操作环境中获得额外的经验，以便微调我们对DTN概念的理解以及值得在实施复杂性方面投资的功能类型。我们预计密钥管理、拥塞处理、多播功能和路由仍将是研究和开发的活跃领域，并且DTN可能至少在未来几年内继续成为活跃的研究奋进。
We review the rationale behind the current design of the Delay/Disruption Tolerant Networking (DTN) Architecture and highlight some remaining open issues. Its evolution, from a focus on deep space to a broader class of heterogeneous networks that may suffer disruptions, affected design decisions spanning naming and addressing, message formats, data encoding methods, routing, congestion management and security. Having now achieved relative stability with the design, additional experience is required in long-running operational environments in order to fine tune our understanding of DTN concepts and the types of capabilities that are worth the investment in implementation complexity. We expect key management, handling of congestion, multicasting capability, and routing to remain active areas of research and development, and that DTN may continue to be an active research endeavor for at least the next few years.
