A New Internet-Draft is available from the on-line Internet-Drafts directories.
Title : Delay-Tolerant Network Architecture
Author(s) : V. Cerf, et al.
Filename : draft-irtf-dtnrg-arch-02.txt
Pages : 23
Date : 2004-7-19
This document describes an architecture for delay-tolerant networks,
and is a generalization of the architecture originally designed for
the Interplanetary Internet: a communication system to provide
Internet-like services across interplanetary distances in support of
deep space exploration. This document describes a generalization of
this architecture that addresses a variety of internetworks with
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 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.
