Title: Delay-Tolerant Network Architecture
State: Active
Authors: Vinton Cerf
Group: Individual Submissions (none)
Date: 2004-07-19
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.
