本文档描述了延迟容忍和中断容忍网络的架构，是最初为星际互联网设计的架构的演变，星际互联网是一种通信系统，旨在跨星际距离提供类似互联网的服务，以支持深空探索。本文档描述了一种架构，该架构解决了具有操作和性能特征的互联网络的各种问题，这些问题使得传统的（类似互联网的）联网方法不可行或不切实际。我们定义了一个面向消息的覆盖层，它存在于其互连的网络的传输（或其他）层之上。该文档介绍了该架构的动机、架构概述、对其操作所需的状态管理的回顾以及对应用程序设计问题的讨论。本文件代表了 IRTF DTN 研究小组的共识，并经过该小组的广泛审查。本备忘录为互联网社区提供信息。
This document describes an architecture for delay-tolerant and disruption-tolerant networks, and is an evolution of the architecture originally designed for the Interplanetary Internet, a communication system envisioned to provide Internet-like services across interplanetary distances in support of deep space exploration. This document describes an architecture that addresses a variety of problems with internetworks having operational and performance characteristics that make conventional (Internet-like) networking approaches either unworkable or impractical. We define a message- oriented overlay that exists above the transport (or other) layers of the networks it interconnects. The document presents a motivation for the architecture, an architectural overview, review of state management required for its operation, and a discussion of application design issues. This document represents the consensus of the IRTF DTN research group and has been widely reviewed by that group. This memo provides information for the Internet community.
