Title : Delay-Tolerant Network Architecture
Author(s) : V. Cerf
Filename : draft-irtf-dtnrg-arch-01.txt
Pages : 29
Date : 2003-10-27
This document describes an architecture for delay-tolerant networks,
and is a generalization of the architecture designed for the
Interplanetary Internet: a communication system to provide Internet-
like services across interplanetary distances in support of deep
space exploration. This generalization addresses networks with
operational and performance characteristics make conventional
networking approaches either unworkable or impractical. We define a
message-based overlay that exists above the transport layer of the
networks on which it is hosted. The document presents an
architectural overview followed by discussions of services, topology,
routing, security, reliability and state management.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
