25 Aug 2003TL;DR: This work proposes a network architecture and application interface structured around optionally-reliable asynchronous message forwarding, with limited expectations of end-to-end connectivity and node resources.
Abstract: The highly successful architecture and protocols of today's Internet may operate poorly in environments characterized by very long delay paths and frequent network partitions. These problems are exacerbated by end nodes with limited power or memory resources. Often deployed in mobile and extreme environments lacking continuous connectivity, many such networks have their own specialized protocols, and do not utilize IP. To achieve interoperability between them, we propose a network architecture and application interface structured around optionally-reliable asynchronous message forwarding, with limited expectations of end-to-end connectivity and node resources. The architecture operates as an overlay above the transport layers of the networks it interconnects, and provides key services such as in-network data storage and retransmission, interoperable naming, authenticated forwarding and a coarse-grained class of service.

TL;DR: This work identifies three fundamental principles that would underlie a delay-tolerant networking (DTN) architecture and describes the main structural elements of that architecture, centered on a new end-to-end overlay network protocol called Bundling.
Abstract: Increasingly, network applications must communicate with counterparts across disparate networking environments characterized by significantly different sets of physical and operational constraints; wide variations in transmission latency are particularly troublesome. The proposed Interplanetary Internet, which must encompass both terrestrial and interplanetary links, is an extreme case. An architecture based on a "least common denominator" protocol that can operate successfully and (where required) reliably in multiple disparate environments would simplify the development and deployment of such applications. The Internet protocols are ill suited for this purpose. We identify three fundamental principles that would underlie a delay-tolerant networking (DTN) architecture and describe the main structural elements of that architecture, centered on a new end-to-end overlay network protocol called Bundling. We also examine Internet infrastructure adaptations that might yield comparable performance but conclude that the simplicity of the DTN architecture promises easier deployment and extension.

TL;DR: 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.
Abstract: 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.

TL;DR: It is expected that key management, handling of congestion, multicasting capability, and routing will 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.
Abstract: 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.
