Abstract

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.
