µD3TN
Simplify data transfer in delay-, disruption-, and disaster-tolerant networks.
µD3TN is a field-tested free software protocol stack for Delay-tolerant Networking. It runs on POSIX and Linux operating systems and can be easily adapted to a variety of challenged networks. The source code is available under BSD license.
Feel free to contact us for support to integrate µD3TN into your own networking project!

µD3TN can be operated on top of different lower-layer protocols. An adaptation to additional protocols via dedicated Convergence Layer Adapters is straight-forward due to its modular design.

µD3TN can be accessed by the application layer via plain IPC as well as TCP sockets. Thus, it can be easily integrated into existing systems and data transfer via any challenged network can be implemented in a very straight-forward manner.

µD3TN leverages standard protocols, which renders it possible to reuse its codebase in various projects. Thus, instead of developing a full networking stack for a challenged network, it is typically only necessary to integrate µD3TN into the application context. The efficient implementation can be operated even on low-cost microcontrollers.

TECHNICAL DETAILS

The Delay-/Disruption Tolerant Networking (DTN) Architecture describes a composition of services and protocols which are necessary for data exchange in challenged networks. In contrast to the protocols of the TCP/IP stack, which require a stable end-to-end connection between the peers, network nodes in DTN can exchange data even without this prerequisite through mechanisms such as store and forward, custody transfer, and late binding.

The main component of the DTN architecture is the Bundle Protocol, which establishes an overlay network agnostically from the underlying layers. A generic interface, called a Convergence Layer Adapter, enables the Bundle Protocol to connect heterogeneous networks.

DTN Node Overview
DTN Network Applications Overview

With μD3TN (formerly μPCN) we have published the world's first implementation of the Bundle Protocol Version 7, which can also be used on microcontrollers in addition to POSIX-based systems due to its lean and hardware-near programming.

To make it easy and painless for users to participate in DTNs, μD3TN provides an interface that allows sending and receiving messages to and from DTN nodes through a simple Application Agent Protocol (AAP).
