Internet Computing, IEEE, Volume 10, Issue 4, July-August 2006 Page(s): 72 - 78

Abstract: “The authors give an overview of current work on delay- and disruption-tolerant networking and review the overall architecture proposed by the Internet Research Task Force's Delay Tolerant Networking Research Group. Their approach to networking makes no assumption that nodes will have end-to-end connectivity, which could be missing with extremely high-latency connections, if the nodes are only in contact with one another infrequently or if contacts are being continually disrupted. They also describe the main protocols the group is developing and give examples of some pilot networks that use these protocols.”

“A Delay-Tolerant Network Architecture for Challenged Internets”,
in Proc. SIGCOMM, August 2003

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.”

“Delay-Tolerant Networking: An Approach to Interplanetary Internet”,
Communications Magazine, IEEE, Volume 41, Issue 6, June 2003 Page(s): 128 - 136

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 [1], 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 delaytolerant 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.”
